Palladium-catalyzed intermolecular 1,3-dienylation of propargyl esters with alcohols for constructing polysubstituted 1,3-dienes

Abstract

Palladium-catalyzed nucleophilic substitution of propargylic esters using alcohols as nucleophiles has been developed, wherein monohydric alcohols allow the formation of trisubstituted 2-alkoxy-1,3-dienes, while the employment of ethylene glycol leads to the synthesis of 1,4-dioxane derivatives through a double substitution process.
