tlooto Summary

Reductive ring openings of carbohydrate benzylidene acetals using borane-trimethylamine and aluminium chloride are described with regioselectivity and solvent dependence.

Abstract

Regioselective reductive ring openings of 4, 6-O-benzylidene acetals of hexopyranosides are described using borane trimethylamine-aluminium chloride. Using toluene as solvent, 4-O-benzyl ethers with the 6-OH free are obtained. Using tetrahydrofuran as solvent. 6-O-benzyl ethers with the 4-OH free are obtained.
