3β-Acet-oxy-19-hy-droxy-Δ(5)-pregnen-20-one.

ABSTRACT: In the title compound, C(23)H(34)O(4), the C/D and D/E rings are trans fused and the A/B ring possesses an anti fusion. The two cyclo-hexane rings adopt a chair conformation while the cyclo-hexene ring exhibits a half-chair conformation. The cyclo-pentane ring displays an envelope conformation with the C atom bearing the methyl group as the flap. In the crystal, the mol-ecules are linked by O-H⋯O hydrogen bonds, forming chains along the b axis.

3β-Acet-oxy-6-hy-droxy-imino-cholestane.

Project description:Two independent mol-ecules comprise the asymmetric unit of the title cholestane derivative, C(29)H(49)NO(3) {systematic name: (3S,8S,9S,10R,13R,14S,17R)-17-[(1R)-1,5-dimethyl-hex-yl]-6-hy-droxy-imino-10,13-dimethyl-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetra-deca-hydro-1H-cyclo-penta-[a]phenanthren-3-yl ace-tate}. The major differences between the mol-ecules relate to the relative orientations of the terminal acetyl [C-C-O-C torsion angles = -158.8 (3) and -81.7 (3)°] and alkyl groups [C-C-C-C = 168.9 (3) and 65.8 (4)°]. In the crystal, the independent mol-ecules associate via pairs of O-H⋯N hydrogen bonds, forming dimeric aggregates. Supra-molecular layers in the ab plane are mediated by C-H⋯O inter-actions.

(+)-Methyl 3β-acet-oxy-13-carb-oxy-19-hy-droxy-11-oxo-C-norolean-18-en-30-oate γ-lactone.

Project description:The title compound, C(33)H(46)O(7), is an unusual oxydation product of the therapeutic agent glycyrrhetinic acid that has, in comparison to the latter, a distinctly altered triterpene structure with one five- and four six-membered carbocycles complemented by a γ-lactone ring with a spiro-junction and a ring double bond. The junction between the five-membered ring C, a cyclo-penta-none ring, and the six-membered ring D, previously in question, was found to be cis, confirming earlier structure assignments based solely on chemical transformations. In the solid state, the compound exhibits five intra- and four inter-molecular C-H⋯O inter-actions with H⋯O distances less than or equal to 2.70 Å and C-H⋯O greater than 100°.

17?-Acet-oxy-11?-hy-droxy-6?-methyl-pregn-4-ene-3,20-dione.

Project description:The title compound, C(24)H(34)O(5), a fungal-transformed metabolite of the injecta-ble contraceptive medroxyprogesterone acetate, consists of four fused rings (A, B, C and D; steroid labelling). Ring A exists in a half-chair conformation while trans-fused rings B and C adopt chair conformations. The five-membered ring D adopts an envelope conformation with the C atom bound to the methyl group at the flap. In the crystal, adjacent mol-ecules are linked by O-H?O and C-H?O hydrogen bonds, forming infinite chains along the a axis.

3β-Acet-oxy-8β,10β-dihy-droxy-6β-meth-oxy-eremophil-7(11)-en-8,12-olide.

Project description:The title compound, C(18)H(26)O(7), is an eremophilenolide which has been isolated from the plant Ligularia duciformis for the first time. The present study confirms the atomic connectivity assigned on the basis of (1)H and (13)C NMR spectroscopy. The mol-ecule contains three fused rings, two six-membered rings in chair confomations and a five-membered ring in a flattened envelope conformation. Two hy-droxy groups are involved in formation of intra- and inter-molecular O-H⋯O hydrogen bonds. The latter ones link mol-ecules into chains propagating in [010].

3β-Acet-oxy-5α-cholestan-6-one 2-cyano-acetyl-hydrazone.

Project description:The asymmetric unit of the title compound, C(32)H(51)N(3)O(3), consists of two crystallographically independent mol-ecules, A and B; the 2-methyl-pentane group of mol-ecule A and the propane group of mol-ecule B are each disordered over two sets of sites, with refined site-occupancies of 0.825 (5):0.175 (5) and 0.630 (18):0.370 (18), respectively. In both mol-ecules, the three cyclo-hexane rings in the steroid fused ring systems adopt chair conformations while the cyclo-pentane rings adopt envelope and twist conformations in mol-ecules A and B, respectively. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link the two independent mol-ecules together, generating R(2) (1)(7) and R(2) (2)(8) ring motifs.

Crystal structure of (20S)-21-[4-(2-hy-droxy-propan-2-yl)-1H-1,2,3-triazol-4-yl]-20-(4-methyl-pent-yl)-5-pregnen-3β-ol with an unknown solvate.

Project description:In the title cholesterol analogue, [systematic name: (3S,8S,9S,10R,13S,14S,17R)-17-{(S)-1-[4-(2-hy-droxy-propan-2-yl)-1H-1,2,3-triazol-1-yl]-6-methyl-heptan-2-yl}-10,13-dimethyl-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetra-deca-hydro-1H-cyclo-penta-[a]phenanthren-3-ol] C32H53N3O2, a new chain, including an inter-mediate triazole and a tertiary hydroxyl group in the terminal position, has been added at position 20 inducing a change in its stereochemistry. In the crystal, mol-ecules are linked by O-H⋯O and O-H⋯N hydrogen bonds, forming layers lying parallel to (-201) and enclosing R44(36) ring motifs. The isopropyl group is disordered about two positions with a refined occupancy ratio of 0.763 (5):0.237 (5). A region of disordered electron density was corrected for using the SQUEEZE routine in PLATON (Spek (2015). Acta Cryst. C71, 9-18). The given chemical formula and other crystal data do not take into account the unknown solvent mol-ecule(s).

3β-Hy-droxy-lup-20(29)-en-28-yl 1H-imidazole-1-carboxyl-ate.

Project description:The title triterpene, C(34)H(52)N(2)O(3), is a C-28 carbamate derivative of betulin prepared in a one-step reaction from the commercially available 1,1'-carbonyl-diimidazole (CDI). All rings are fused trans. The X-ray study shows the retention of the configuration of C-28 with respect to the known chiral centres of the molecule. In the crystal, the mol-ecules are O-H⋯O hydrogen bonded via the hy-droxy group and the carbonyl group of the carbamate function into chains running along the c axis. A quantum-mechanical ab initio Roothaan Hartree-Fock calculation of the equilibrium geometry of the isolated mol-ecule gives values for bond-lengths and valency angles close to the experimental values. The calculations also reproduce the mol-ecular conformation well, with calculated puckering parameters that agree well with the observed values.

3β-Acet-oxy-lup-20(29)-en-28-yl 1H-1,2,4-tri-azole-1-carboxyl-ate.

Project description:The title triterpene, C(35)H(53)N(3)O(4), is a C-28 carbamate derivative of 3β-acet-oxy-betulin prepared in a one-step reaction from the commercially available 1,1'-carbonyl-di(1,2,4-triazole) (CDT), crystallized from acetone/n-hexane. All rings are trans fused. The carbamate and acetate substituents are in axial and equatorial positions, respectively. A quantum chemical ab initio Roothaan Hartree-Fock calculation of the equilibrium geometry of the isolated mol-ecule gives values for bond lengths and valency angles in close agreement with experimental values. The calculation also reproduces the observed mol-ecular conformation, with puckering parameters that agree well with those determined from the crystallographic study.

7-Hy-droxy-6-meth-oxy-2H-chromen-2-one.

Project description:The title compound, C(10)H(8)O(4), is one of the coumarins existing in Morinda citrifolia L (Noni). The chromenone ring system is approximately planar with a maximum deviation of 0.0208 (14) Å. The meth-oxy group does not deviate from this plane [C-O-C-C torsion angle = -1.5 (3)°], indicating that the whole mol-ecule is almost planar. In the crystal packing, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains. These are further connected by C-H⋯O hydrogen bonds.

3β-Acet-oxy-12α-chloro-d-friedooleanan-28,14β-olide.

Project description:The title compound, C(32)H(49)ClO(4), was obtained along with nitrile and lactam products in the POCl(3)-catalysed Beckmann rearrangement from 3β-acet-oxy-12-hydroxyiminoolean-28-olic acid methyl ester. The mechanism of the transformation leading to the title compound remains unclear and requires further investigation. Rings A, B and E are in chair conformations, ring C has a twisted-boat conformation, ring D a conformation halfway between boat and twisted-boat and rings D and E are cis-fused. In the crystal, mol-ecules are connected by weak inter-molecular C-H⋯O hydrogen bonds into layers extending parallel to the bc plane.
