The Alkoxy Substitution Reaction on α-Oxo Ketene Dithioacetals: A New Access to α-Oxo Ketene O,S-/O,O-Acetals

Abstract

The substitution reaction of alkylthio group of α,α′-dioxo ketene dibenzylthioacetals by alkoxy group was performed successfully. This transformation provides a facile route to the useful α,α′-dioxo ketene O,S- and O,O-acetals.

Keywords:

• α-Oxo ketene dithioacetals
• Dimethylthioacetals
• α-Oxo ketene O,S-/O,O-acetals
