with ethyl formate in the presence of sodium methoxide afforded sodium (2-methyl-6-oxocyclohexylidene)methanolate which reacted with aminopyrazoles, aminotriazole, and aminotetrazole to produce fused quinazoline derivatives; its reactions with cyanothioacetamide, cyanoacetamide, and cyanoacetohydrazide gave tetrahydroquinoline-3-carbonitrile derivatives. The reactions of 8-methyl-2-sulfanyl-5,6,7,8-te
摘要 在甲醇钠存在下用甲酸乙酯处理3-甲基环己酮,得到(2-甲基-6-氧代环己基)甲醇钠,其与氨基吡唑,氨基三唑和氨基四唑反应生成稠合的喹唑啉衍生物。其与氰基硫代乙酰胺,氰基乙酰胺和氰基乙酰肼反应,得到四氢喹啉-3-甲腈衍生物。8-甲基-2-硫烷基-5,6,7,8-四氢喹啉-3-腈与烷基化剂的反应导致噻吩并[2,3- b ]喹啉衍生物的形成。使用B3LYP / 6-311 + G **和HF / 6-311 + G **近似进行了合成化合物的DFT计算研究。计算得出的HOMO和LUMO能量表明,电荷转移发生在它们的分子中。
