Bromodimethylsulfonium bromide catalyzed synthesis of methyl 2-dexoy-4,6-o-benzylidene galactopyranoside from galactal and the rapid route to 2,3- and 2,6-dideoxygalactopyranoses

4,6-O-Benzylidenation of D-galactal with PhCH(OCH3)2 catalyzed by bromodimethylsulfonium bromide leads to methyl 2-dexoy-4,6-O- benzylidene galactopyranoside efficiently, which serves as a key intermediate to the ready preparation of

The Synthesis of (2S,3R)-2-Hydroxymethylpiperidin-3-ol, a Fragment of the Alakloid Swainsonine

Methyl α- and β-D-galactopyranoside have been converted into methyl 4,6-di-O-benzyl-2,3-dideoxy-α- and -β-D-threo-hexoside, and subsequent treatment with ethanedithiol gives the same alcohol.Tosylation and azide displacement gives, after hydrolysis, an az
