3-(Naphthalene-2-carbonyl)-pyrrolo(2,1-A)isoquinoline-1-carboxylic acid ET ester;ethyl 3-(naphthalene-2-carbonyl)pyrrolo[2,1-a]isoquinoline-1-carboxylate
Pyrrolo[2,1-a]isoquinoline derivatives were synthesized by one-pot three-component reactions starting from isoquinoline, 2-bromoacetophenones and different non-symmetrical acetylenic dipolarophiles using 1,2-epoxypropane as solvent. The structure of the compounds was assigned by IR and NMR spectroscopy.
