Abstract
Desilylation of α-alkoxysilanes offers the convenient generation of carbinyl carbanions which react with a variety of carbonyl compounds giving mono-protected 1, 2-diols of unsymmetrical type. Dehydration of these unsymmetrical diols leads to the regioselective formation of methyl ketones.
