Abstract
Methyl 2-(2-benzoylphenylamino)-2-oxoacetate and dimethyl 2,2′-(4,4′-methylenebis(4,1- phenylene)bis(azanediyl)) bis(2-oxoacetate) undergo a smooth reaction with triphenylphosphine and dialkyl acetylenedicarboxylates to produce corresponding highly functionalised 5-oxo-4,5-dihydro-1H-pyrroles and 5-oxo-2,5-dihydro-1H-pyrroles derivatives.
