Abstract:	Summary. The regioselective reaction of N¹-benzyl-N²-(4-nitrophenyl)ethanediamide with dialkyl acetylenedicarboxylates or alkyl propiolates in the presence of triphenylphosphine leads to dialkyl 4-benzylamino-1-(4-nitrophenyl)-5-oxo-2,5-dihydro-1H-pyrrole-2,3-dicarboxylates or alkyl 4-benzylamino-1-(4-nitrophenyl)-2-oxo-5-pyrrolidinecarboxylates in good yields.

Keywords:	. Intramolecular Wittig reaction Acetylenic esters Triphenylphosphine 2-Oxo-5-pyrrolidines 5-Oxo-2,5-dihydro-1H-pyrroles.
