Abstract

Abstract A new method has been developed for the preparation of α, β-unsaturated carboxylic acids and corresponding esters with (E)-stereoselectivity via the TiCl 4-mediated olefination of aldehydes. The method, which uses readily available acetic acid or its alkyl esters as active methylene partners, is more flexible and complementary to conventional routes in the preparation of (E)-cinnamic acid derivatives.
