摘要:
A catalytic dihydroxylation reaction on glycals has been developed using a bimetallic oxidizing system to furnish sugar 1,2-diols in a highly setreoselective manner.

Abstract A simple and high-yielding method for the preparation of 1- O - β -acyl derivatives of carbohydrates with an axial OH group at C-2 is described. It utilizes the property of unprotected carbohydrates to preferentially form 1,2- O - cis stannylene acetals, when treated with dibutyltin oxide. These acetals can be acylated with retention of configuration at the anomeric position.
