One-pot, three component reactions between isocyanides and dialkyl acetylenedicarboxylates in the presence of phenyl isocyanate: synthesis of dialkyl 2-(alkyl/arylimino)-2,5-dihydro-5-oxo-1-phenyl-1H-pyrrole-3,4-dicarboxylate

The reactive 1:1 adduct, generated from the reaction between alkyl/aryl iscyanides and dialkyl acetylenedicarboxylates, was trapped by phenyl isocyanate to yield dialkyl 2-(alkyl/arylimino)- 2,5-dihydro-5-oxo-1-phenyl-1H-pyrrole-3,4-dicarboxylate in good yields.
