The synthesis of new spiro derivatives of tetrahydro-2-benzazepine was accomplished and their nitration, bromination, allylation, acetylation, formylation and oxidation reactions were studied. Nitration and bromi-nation of 5-methyl(1,5-dimethyl)-1,2,4,5-tetrahydrospiro[3H-2-benzazepine-3,1-cycloalkane] took place regioselectively on position C-8 of the phenyl ring. A nitrone was obtained for the first
完成了四氢-2-苯并ze庚因的新螺衍生物的合成,并对其硝化,溴化,烯丙基化,乙酰化,甲酰化和氧化反应进行了研究。5-甲基(1,5-二甲基)-1,2,4,5-四氢螺[3 H -2-苯并ze庚因-3,1-环烷烃]的硝化和溴化反应在区域C-8的位置上进行苯环。在标题系列中首次获得了硝酮。化合物的结构通过红外和核磁共振光谱确定。
