Copper-catalyzed cascade reactions of ?,?-unsaturated esters with keto esters.


ABSTRACT: A copper-catalyzed cascade reaction of ?,?-unsaturated esters with keto esters is reported. It features a copper-catalyzed reductive aldolization followed by a lactonization. This method provides a facile approach to prepare ?-carboxymethyl-?-lactones and ?-carboxymethyl-?-lactones under mild reaction conditions.

A copper-catalyzed cascade reaction of α,β-unsaturated esters with keto esters is reported. It features a copper-catalyzed reductive aldolization followed by a lactonization. This method provides a facile approach to prepare γ-carboxymethyl-γ-lactones and δ-carboxymethyl-δ-lactones under mild reaction conditions. ...[more]
