Abstract

1, 3-Dioxolanes are among the most widely used protecting groups for carbonyl compound^.^ The most common methods for the synthesis of these acetals employ protic acids, aqueous conditions, or high temperatures, making them unsuitable for the protection of sensitive compounds. A gentle, low temperature method for the formation of ethylene acetals might involve the acidcatalyzed addition of an epoxide to a ketone. Bogert and ...
