Selective Deoxygenation via Regioselective Thioacylation of Non-protected Glycopyranosides by the Dibutyltin Oxide Method

Regioselective thioacylation of some non-protected glycopyranosides (Me α-D-Glc, Me β-D-Glc, Me α-D-Xyl, Me β-D-Xy1) was examined by the dibutyltin oxide method, using phenoxythiocarbonyl chloride as the thioacylating agent. This method gave the mono-thionocarbonates regioselectively in high yields....
