摘要：

Solvent-free techniques were successfully and efficiently applied under mild conditions to the perbenzylation of methyl alpha-D-glucopyranoside and methyl 6-bromo(and 6-chloro)-6-deoxy-alpha-D-glucopyranoside, and to the selective monobenzylation of diethyl (R,R)-tartrate. Selective 2-O- or 3-O-benzylation of methyl 4,6-O-benzylidene-alpha-D-galactopyranoside requiring CH2Cl2 as solvent, was observed depending on the nature of the ammonium catalyst.
