Preparation of methyl 2,3-di-O-mesyl-4,6-thioanhydro-alpha-D-galactopyranoside and methyl 2-O-mesyl-4,6-thioanhydro-alpha-D-gulopyranoside.

Two 2-oxa-7-thiabicyclo[4.2.0]octane derivatives, 4 and 10, with the D-galacto and D-gulo configuration, respectively, were obtained from methyl alpha-D-glucopyranoside. The thietane cyclization involved a thio-Mitsunobu reaction resulting in a 6-thioacet

Truly catalytic and chemoselective cleavage of benzylidene acetal with phosphomolybdic acid supported on silica gel

Phosphomolybdic acid supported on silica gel provides a truly catalytic method for the chemoselective cleavage of benzylidene acetals having sensitive functional groups under mild conditions. It is easy to perform on large scale owing to minimal catalyst loading (0.5 mol-%). Several sensitive functional groups such as TBDPS ether, -OMs, -OAc, allyl ether, N-Boc, N-Fmoc and N-Cbz are stable under the reaction conditions. In addition, benzylidene acetal is selectively cleaved in the presence of isopropylidene ketal. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
