Abstract

A short, enantioselective synthesis of carbasugars 4a-carba-α- l-xylofuranose 15, 4- epi-validatol 16and their corresponding carboxylic acids 11and 12 is reported. These compounds were prepared via a four-step sequence of nucleophilic addition, ring closure (NARC), dihydroxylation and reduction.
