Abstract

A Bu₃P-mediated mild and efficient synthesis of multi-functional alkenes has been described starting from substituted acrylate with aldehydes. In situ generated zwitterionic intermediates underwent proton-exchange to afford ylide intermediates, which were trapped by corresponding aldehydes providing the products in up to 92% yield with complete E-stereoselectivity. Further derivatization of the products was performed to furnish functional pyridazinones.
