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
已经表明3-(3,3-二甲基-1,2,3,4-四氢异喹啉-1-亚乙基)丙酮酸的甲基酯与硫代氨基脲在冰醋酸中的反应导致杂环化并形成环戊二烯。 3,3-二甲基-1-(5-硫代-1,5-二氢-1,2,4-三唑-3-基亚甲基羰基)-1,2,3,4-四氢异喹啉,但与氨基脲相互作用相同的条件导致吡咯环的成环。烯氨基酮酯与丙二醛缩合后,2-氰基-4-二氰基亚甲基-5-(3,3-二甲基-1,2,3.4-四氢异喹啉-1-亚基)-3-氧代戊酸的腈为形成。
