Enzyme-based discrimination between clockwise and counterclockwise isomers of unsymmetrically disubstituted β-cyclodextrins. 6A,6B- and 6A,6G-derivatives
A complete set of β -cyclodextrins 6A, 6X-diactivated by two different sulfonyl groups
摘要:
Each of 6A-O-(p-nitrobenzenesulfonyl)-6x-O-(beta-naphthalenesulfonyl)-beta-cyclodextrins (X = B-G) was prepared by the reaction of 6-O-(beta-naphthalenesulfonyl)-beta-cyclodextrin with p-nitrobenzenesulfonyl chloride, isolated, and structurally determined through selective chemical conversion.
