Stereoselective synthesis of 1,2,3,4-tetrasubstituted dienes from allenoates and aldehydes: An observation of phosphine-induced chemoselectivity

(Equation Presented). Phosphine-mediated olefination between α-substituted allenoates and aldehydes to form 1,2,3,4-tetrasubstituted 1,3-dienes is presented. High levels of chemo-and diastereoselectivity and yield are obtained for a wide scope of substrates with the choice of appropriate phosphines. This reaction evidences the capacity of phosphines in the control of reaction pathways and provides a highly efficient synthetic method for tetrasubstituted conjugated dienes.
