Catalytic Asymmetric Desymmetrization of Cyclic <i>m</i><i>eso</i>-1,3- and 1,4-Diols by a Phosphinite Derivative of Quinidine

Abstract

Asymmetric monobenzoylation reactions of cyclic meso-1,3- and 1,4-diols were catalyzed by a phosphinite derivative of quinidine to afford the corresponding monobenzoylated diol with good yield and enantioselectivity. [reaction: see text]
