Palladium-CatalyzedIntermolecular 1,3-Dienylationof Propargyl Esters Involving the Insertion of SO<sub>2</sub>

A palladium-catalyzed three-component 1,3-dienylation of propargylic esters with DABSO and aryl iodides has been developed. This novel reductive cross-coupling reaction produces 2-sufonylated 1,3-dienes as single products in the presence of reductive metal Mn with high regio- and chemoselectivities. Control experiments demonstrated that the transformation may undergo a radical process.

Abstract

A palladium-catalyzed three-component 1,3-dienylation of propargylic esters with DABSO and aryl iodides has been developed. This novel reductive cross-coupling reaction produces 2-sufonylated 1,3-dienes as single products in the presence of reductive metal Mn with high regio- and chemoselectivities. Control experiments demonstrated that the transformation may undergo a radical process.
