Abstract

The cyclic thionocarbonates give O, S-rearrangement products, the thiolcabonates, in appreciable yields, when treated with a catalytic amount of tributyltin hydride and α, α- azobisisobutyronitrile. This reaction opens a new route to regioselective preparation of thio- sugars under very mild conditions.
