1-a]isoquinolines with binucleophiles such as 2-amino-4-methyl-phenol, o-aminothiophenol, and caprolactam hydrazidine proceeds with opening of the dioxopyrroline ring and is accompanied by heterocyclization to give heteroaromatic benzoxazole, benzothiazole, and 1,2,4-triazole systems. Heterocyclization does not occur in the reaction of o-hydroxybenzylamine, o-aminobenzyl alcohol, and the hydrazide of anthranilic

Reactions of 5,5-dialkyl-2,3,4,5-tetrahydropyrrolo[2,1-a]isoquinoline-2,3-diones with o-phenylenediamine in the presence of a catalytic amount of hydrogen chloride or p-toluenesulfonic acid involved opening of the pyrrole ring with formation of 3-(3,3-dialkyl-1,2,3,4-tetrahydroisoquinolin-1-ylidenemethyl)quinoxalin-2(1H)-ones. The presence of an enamine fragment in the products was confirmed by reaction with oxalyl chloride.
