Tóm tắt

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.
