Abstract: A palladium catalyzed tandem reaction between ortho-functionalized aryl enones and 2,4-dienyl carbonates has been presented, proceeding through sequential 2,4-dienylation/Michael addition/π-σ-π isomerization/allylic alkylation. A broad array of enantioenriched architectures having fused and spirocyclic frameworks are constructed… read more here.

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… read more here.
