Generation and Trapping of 2-Methyl-3-phenyl-4-oxoquinazolinium-1-methanide: Routes to Pyrrolo[1,2-a]quinazolinones

Abstract

Azomethine ylide, prepared from quinazolinium salt, undergoes 1,3-dipolar cycloaddition with alkyne dipolarophiles to produce substituted pyrroles. In fact, when alkene dipolarophiles were introduced, a novel compound i.e., substituted pyrrolo[1,2-a]quinazolinones have resulted from this work.
