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
