Direct 2,3-O-Isopropylidenation of α-d-Mannopyranosides and the Preparation of 3,6-Branched Mannose Trisaccharides

A highly efficient, regioselective method for the direct 2,3-O-isopropylidenation of α-d-mannopyranosides is reported. Treatment of various α-d-mannopyranosides with 0.12 equiv of the TsOH·H(2)O and 2-methoxypropene at 70 °C gave 2,3-O-isopropylidene-α-d-mannopyranosides directly in 80%~90% yields....
