The reaction of benzylideneaniline with dimethyl acetylenedicarboxylate in the presence of water has been re-examined.The structure previously proposed for the product was found to be incorrect.The product is shown to be methyl 4-hydroxy-5-oxo-1,2-diphenyl-3-pyrroline-3-carboxylate (3).Similar products were obtained from benzylideneanisidine and anisylideneaniline.
