Abstract
The partial alkylation of methyl 4,6-O-benzylidene-α-D-galactopyranoside in dimethylformamide and dimethyl sulfoxide in the presence of barium oxide and hydroxide is described. It has been shown that methylation and benzylation lead predominantly to the 3-alkyl derivatives with yields of 30–40%, benzylation taking place more selectively than methylation. The compounds synthesized have been characterized by their melting points and specific rotations.
