Abstract

Discussion Cycloaddition reactions of 2-aroyl-1, 2-dihydroisoquinaldonitrile hydrofluoroborates (5) with substituted ethyl cinnamates (6) were carried out in dimethylformamide solution at room temperature and were found to give mixtures of two isomeric isoquinolylpyrroles of types 7 and 8 (eq 1). In all cases, no matter what the substituents
