摘要

Abstract A useful methodology for the synthesis of a number of 2-, 3-and 2, 3-disubstituted deoxynojirimycin analogs is reported. It has been found that the epoxides in stereoselectively synthesized N-carboalkoxy-2, 3-anhydro-1-deoxymannojirimycins (4 and 5) react with N-, S-and F-nucleophiles to give a mixture of gluco and altro products. The 3- azido altro compound (12b) yields the desired gluco derivative (40) by oxidation, in situ ...
