Abstract

The intermediate phosphorus ylides which were prepared by reaction between triphenylphosphine and imidazole-4-carbaldehyde in the presence of acetylenic diesters produce dialkyl 5H-pyrrolo[1,2-c]imidazole-5,6- dicarboxylate derivatives via intramolecular Wittig reaction.

Keywords: Dialkyl 5H-pyrrolo[1,2-c]imidazole-5,6-dicarboxylates, imidazole-4-carbaldehyde, Acetylenic esters, Triphenylphosphine
