## 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)
