It has been shown that the reaction of the methyl ester of 3-(3,3-dimethyl-1,2,3,4-tetrahydroisoquinolin-1-idene)pyruvic acid with thiosemicarbazide in glacial acetic acid leads to heterocyclization with the formation of 3,3-dimethyl-1-(5-thioxo-1,5-dihydro-1,2,4-triazol-3-ylmethylidenecarbonyl)-1,2,3,4-tetra-hydroisoquinoline, but the interaction with semicarbazide under the same conditions leads

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

2,3-Dioxpyrrolo[2,1-a]isoquinolines react with 1,8-naphthalenediamine in 2-propanol in the presence of p-toluenesulfonic acid to give 2-spiro-(1,2-dihydroperimid-2-yl)-5,5-dialkyl-2,3,5,6-tetrahydro-pyrrolo[2,1-a]isoquinolin-3-ones whose structure was confirmed by X-ray analysis.
