The paper reports selective mono-etherification of the 2-, and 3-hydroxyl groups of methyl 4,6-O-isopropylidene-α-d-mannopyranoside using tin(II) chloride catalysed reactions of diaryldiazomethanes. By the use of different diazo compounds and the variatio

Highly regioselective monoalkylations of the cis-2,3-diol group in mannopyranosides can be achieved with diaryldiazoalkanes in the presence of catalytic amounts of tin(II) chloride.With diazo(diphenyl)methane (1), its 4,4'-dimethyl (2) and 4,4'-dichloro (
