As part of a programme involving X-ray crystallographic studies" of cis-and tpuns-fused hexopyranosides, we now report on the crystal structures of methyl 2-~-methyl-~-D-glucop~anoside\* (11, which was obtained by debe~lidenation of methyl 4,~-O-benzyIidene-2-O-methyI-3-O-~-tolylsulfonyl-~-~-glucopy
## Abstract Methyl 2‐__O__‐benzyl‐6‐deoxy‐3‐__C__‐methyl‐α‐D‐mannopyranoside (2) was synthesized in ten steps by starting from the readily available methyl 2,3‐anhydro‐4,6‐__O__‐benzylidene‐α‐D‐allo‐pyranoside (3). The key step was the stereoselective __cis__‐hydroxylation (cat. osmium(VIII) oxide)
