Supramolecular docking structure determination of alkyl-bearing molecules.

ABSTRACT: Numerous natural products and drugs contain flexible alkyl chains. The resulting conformational motion can create challenges in obtaining single crystals and thus determining their molecular structures by single-crystal X-ray diffraction (SCXRD)^1-11. Here we demonstrate that by using pillar[5]arene-incorporated metal-organic frameworks (MOFs) and taking advantage of pillar[5]arene-alkyl chain host-guest recognition^12-15, it is possible to reduce this motion and bring order to alkyl-chain-containing molecules as the result of docking within accessible pillar[5]arene units present in an overall MOF. This has allowed the single-crystal structures of 48 alkyl-chain-containing molecules, including 6 natural products, 2 approved drugs and 18 custom-made compounds collected
