One-step synthesis and some reactions of ethyl 10-(ethoxycarbonyl-3,4-dimethylpyrrol-2-yl)-1,2-dimethylpyrrolo[1,2-b]isoquinoline-3-carboxylate

Abstract

The title compound 2 has been synthesized by the acid-catalysed condensation of ethyl 3,4-dimethylpyrrole-2-carboxylate 1 with phthalaldehyde and its structure has been confirmed spectroscopically. The photodimerization and Diels–Alder reactions of compound 2 have been investigated. The X-ray crystal structure of the photodimer 3, which indirectly provides evidence for the identity of compound 2, has been determined.
