Vicinal 1,2-difunctionalization of alkynones and alkynoates with glycosyl thiosulfonates: Stereoselective synthesis of fully substituted glycosylthio-functionalized α,β-Unsaturated sulfones.

A simple and efficient vicinal 1,2-glycosylthiosulfonylation of alkynones and alkynoates has been developed using readily accessible glycosyl thiosulfonates under metal-free conditions. Under the catalysis of 10 mol% Cs2CO3, a broad range of alkynones and alkynoates underwent smooth Michael addition/nucleophilic substi...
