Three benzoindolizine derivatives, 1, 2, and 3, were obtained via 1,3-dipolar cycloaddition. The reaction of 1-(2′-benzimidazolylmethyl)isoquinolinium ylides with dimethyl acetylenedicarboxylate gave a mixture of pyrrolo[2,1- a]isoquinoline-1,2-dicarboxylate ( 1) and 1,10b-dihydropyrrolo[2,1- a]isoquinoline-1,2-dicarboxylate ( 2) derivatives containing a benzimidazole moiety. The reaction of this isoquinolinium N-ylide with dimethyl maleate gave an unexpected 2,3-dihydropyrrolo[2,1- a]isoquinoline-1,2-dicarboxylate ( 3). The structures of all reported compounds have been examined by X-ray crystallography, mass spectrometry, and NMR spectroscopy. [ABSTRACT FROM AUTHOR]
