Active Ester Functionalized Azobenzenes as Versatile Building Blocks.

ABSTRACT: Azobenzenes are important molecular switches that can still be difficult to functionalize selectively. A high yielding Pd-catalyzed cross-coupling method under mild conditions for the introduction of NHS esters to azobenzenes and diazocines has been established. Yields were consistently high with very few exceptions. The NHS functionalized azobenzenes react with primary amines quantitatively. These amines are ubiquitous in biological systems and in material science.

Fluorinated azobenzenes as supramolecular halogen-bonding building blocks.

Project description:ortho-Fluoroazobenzenes are a remarkable example of bistable photoswitches, addressable by visible light. Symmetrical, highly fluorinated azobenzenes bearing an iodine substituent in para-position were shown to be suitable supramolecular building blocks both in solution and in the solid state in combination with neutral halogen bonding acceptors, such as lutidines. Therefore, we investigate the photochemistry of a series of azobenzene photoswitches. Upon introduction of iodoethynyl groups, the halogen bonding donor properties are significantly strengthened in solution. However, the bathochromic shift of the π→π* band leads to a partial overlap with the n→π* band, making it slightly more difficult to address. The introduction of iodine substituents is furthermore accompanied with a diminishing thermal half-life. A series of three azobenzenes with different halogen bonding donor properties are discussed in relation to their changing photophysical properties, rationalized by DFT calculations.

Amine-Functionalized Spin Crossover Building Blocks.

Project description:Bistable spin crossover complexes such as [Fe{HB(pz)3}2] (pzH = pyrazole) show promise for sensor applications and electrically-controlled data storage units, but exploiting their potential hinges on their integration into a functional environment. We here present a system enabling such covalent post-functionalization steps in both symmetric and asymmetric patterns, based on the amine-functionalized complex [Fe{HB(4-NH2pz)(pz)2}2], obtained by reduction of the nitro analogue. The building block aspects of [Fe{HB(4-NH2pz)(pz)2}2] are showcased by its transformation into amide, imine and azo derivatives, which are structurally and magnetically characterized. All tris(pyrazolyl)borate complexes retain the spin crossover properties of their parent compound, with spin crossover temperatures ranging from 350 to 430 K. The transition parameters are correlated with the electronic properties of the functionalizing group, opening the possibility of fine-tuning the spin crossover properties of the building block as it is integrated in the environment of choice.

Versatile synthesis of pathogen specific bacterial cell wall building blocks.

Project description:Full details on the design, strategies and tactics for development of a novel synthetic sequence to farnesyl lipid I and II analogs is reported. The modular route was based on a three coupling strategy involving an efficient solid phase synthesis of the elaborate peptide fragment, which proceeded with excellent yield and stereoselectivity and was efficiently applied for the convergent synthesis of 3-lipid I and II. Furthermore, the generality of this route was demonstrated by synthesis of 3-lipid I congeners that are characteristic for S. aureus and E. faecalis. All 3-lipid I and II building blocks were obtained in high purity revealing high spectroscopic resolution.

Functionalized C3-Symmetric Building Blocks—The Chemistry of Triaminotrimesic Acid

Project description:A series of C3-symmetric fully substituted benzenes were prepared based on alkyl triamino-benzene-tricarboxylates. Starting with a one step-synthesis, the alkyl triamino-benzene-tricarboxylates were synthesized using the corresponding cyanoacetates. The reactivity of these electronically sophisticated compounds was investigated by the formation of azides, the click reaction of the azides and a Sandmeyer-like reaction. Caused by the low stability of triaminobenzenes, direct N-alkylation was rarely reported. The use of the stable alkyl triamino-benzene-tricarboxylates allowed us total N-alkylation under standard alkylation conditions. The molecular structures of the C3-symmetric structures have been corroborated by an X-ray analysis.

Novel peptoid building blocks: synthesis of functionalized aromatic helix-inducing submonomers.

Project description:Peptoids, oligo-N-substituted glycines, can fold into well-defined helical secondary structures. The design and synthesis of new peptoid building blocks that are capable of both (a) inducing a helical secondary structure and (b) decorating the helices with chemical functionalities are reported. Peptoid heptamers containing carboxamide, carboxylic acid or thiol functionalities were synthesized, and the resulting peptoids were shown to form stable helices. A thiol-containing peptoid readily formed the homodisulfide, providing a convenient route to prepare peptoid helix homodimers.

Scalable Synthesis of Versatile Rare Deoxyamino Sugar Building Blocks from d-Glucosamine.

Project description:We report the syntheses of 1,3,4-tri-O-acetyl-2-amino-2,6-dideoxy-β-d-glucopyranose and allyl 2-amino-2,6-dideoxy-β-d-glucopyranoside from d-glucosamine hydrochloride. The potential of these two versatile scaffolds as key intermediates to a diversity of orthogonally protected rare deoxyamino hexopyranosides is exemplified in the context of fucosamine, quinovosamine, and bacillosamine. The critical C-6 deoxygenation step to 2,6-dideoxy aminosugars is performed at an early stage on a precursor featuring an imine moiety or a trifluoroacetamide moiety in place of the 2-amino group, respectively. Robustness and scalability are demonstrated for a combination of protecting groups and incremental chemical modifications that sheds light on the promise of the yet unreported allyl 2,6-dideoxy-2-N-trifluoroacetyl-β-d-glucopyranoside when addressing the feasibility of synthetic zwitterionic oligosaccharides. In particular, allyl 3-O-acetyl-4-azido-2,4,6-trideoxy-2-trifluoroacetamido-β-d-galactopyranoside, an advanced 2-acetamido-4-amino-2,4,6-trideoxy-d-galactopyranose building block, was achieved on the 30 g scale from 1,3,4,6-tetra-O-acetyl-β-d-glucosamine hydrochloride in 50% yield and nine steps, albeit only two chromatography purifications.

Transition-Metal Phthalocyanines as Versatile Building Blocks for Molecular Qubits on Surfaces.

Project description:The search for molecular or colloidal building units capable of autonomously organized configurations has been a long-standing endeavor that has resulted in the development of innovative material categories, such as metal-organic and covalent organic or long-range molecular networks. In particular, the possibility of using molecules on surfaces to create specific architectures, for example, those containing nanostructures of S = 1/2 molecular spin, can enable versatile quantum materials and the exploration of future quantum devices. Transition-metal phthalocyanines are particularly attractive candidates as they are stable molecules that can host spin-bearing transition-metal ions in a planar conjugated ring. Here, we use density functional theory calculations to systematically study electronic and magnetic properties and hyperfine parameters for the whole series of 3d transition-metal atoms. We perform transport simulations of selected qubit candidates to further elucidate their suitability for molecular spin qubits on a surface.

3-Cyanoallyl boronates are versatile building blocks in the synthesis of polysubstituted thiophenes.

Project description:We report the preparation of hitherto unprecedented 3-cyanoallyl boronates using condensation of the parent α-boryl aldehyde and nitriles. The resulting allyl boronates have been used to generate a wide range of borylated thiophenes, which represent a valuable class of heterocycles in modern drug discovery. Subsequent Suzuki-Miyaura cross-coupling enabled the synthesis of pharmaceutically important 3,5-disubstituted aminothiophenes. Moreover, late stage functionalization gave access to borylated bromothiophene and thieno[2,3-b]pyridines.

Locked nucleic acid building blocks as versatile tools for advanced G-quadruplex design.

Project description:A hybrid-type G-quadruplex is modified with LNA (locked nucleic acid) and 2'-F-riboguanosine in various combinations at the two syn positions of its third antiparallel G-tract. LNA substitution in the central tetrad causes a complete rearrangement to either a V-loop or antiparallel structure, depending on further modifications at the 5'-neighboring site. In the two distinct structural contexts, LNA-induced stabilization is most effective compared to modifications with other G surrogates, highlighting a potential use of LNA residues for designing not only parallel but various more complex G4 structures. For instance, the conventional V-loop is a structural element strongly favored by an LNA modification at the V-loop 3'-end in contrast with an alternative V-loop, clearly distinguishable by altered conformational properties and base-backbone interactions as shown in a detailed analysis of V-loop structures.

Synthesis of 5-(Fluoroalkyl)isoxazole Building Blocks by Regioselective Reactions of Functionalized Halogenoximes.

Project description:A comprehensive study on the synthesis of 5-fluoroalkyl-substituted isoxazoles starting from functionalized halogenoximes is reported. One-pot metal-free [3 + 2] cycloaddition of CF3-substituted alkenes and halogenoximes bearing ester, bromo, chloromethyl, and protected amino groups was developed for the preparation of 5-trifluoromethylisoxazoles. The target 3,5-disubstituted derivatives were obtained in a regioselective manner in good to excellent yield on up to 130 g scale. 5-Fluoromethyl- and 5-difluoromethylisoxazoles were synthesized by late-stage deoxofluorination of the corresponding 5-hydroxymethyl or 5-formyl derivatives, respectively, in turn prepared via metal-free cycloaddition of halogenoximes and propargylic alcohol. An alternative approach based on nucleophilic substitution in 5-bromomethyl derivatives was found to be more convenient for the preparation of 5-fluoromethylisoxazoles. Reaction of isoxazole-5-carbaldehydes with the Ruppert-Prakash reagent was used for the preparation of (β,β,β-trifluoro-α-hydroxyethyl)isoxazoles. Utility of described approaches was shown by multigram preparation of side-chain functionalized mono-, di-, and trifluoromethylisoxazoles, for example, fluorinated analogues of ABT-418 and ESI-09.
