Abstract
Abstract Acetoacetanilide undergoes a smooth reaction with triphenylphosphine and dialkyl acetylenedicarboxylates to produce dialkyl 2-(acetoacetanilide-2-yl)-3-(triphenylphosphoranilidene)-butandioates, which undergo intramolecular Wittig reaction to produce 2-methyl-3-( N -phenylcarbonyl)-1,4-dialkoxycarbonylcyclobutenes. These cyclobutene derivatives undergo electrocyclic ring-opening reactions in boiling toluene to produce highly electron-deficient 1,3-dienes.
