  γ-Cyclodextrins possessing an azido group and a triisopropylbenzenesulfonyl group as useful synthetic and authentic intermediates for unsymmetrically functionalized derivatives

  摘要：

  Seven isomers of cyclomaltooctaose (gamma-cyclodextrin) whose C6s were unsymmetrically disubstituted with both an azido group and an arenesulfonyloxy group were prepared and each of them was isolated by reversed phase chromatography. The assignment of the modified positions in each regioisomers was unambiguously performed by chemical correlation with the authentic compounds and chemical conversion to the 3,6-anhydro derivatives followed by high-resolution 2D-H-1 NMR (COSY, TOCSY, and HO-HAHA) analyses. The compounds are versatile synthetic and authentic intermediates to prepare sophisticated derivatives with two different functionalities at desired positions on the molecule for supramolecular chemistry.
