A New Route to Butane-1,2-diacetals and the Development of Alternative Substitution Patterns to Facilitate Differential Protection of the Products

Abstract

The utility of 2,3-dialkoxybutan-1,3-dienes as reagents for the protection of vicinal diols and α-hydroxy acids as their corresponding 1,2-diacetals is demonstrated together with their later deprotection under mild reaction conditions.
