2-methylaminotropone (II), and 2-dimethylaminotropone (III) were investigated. The structure of the products was proved by hydrolysis to lead to known tropolonederivatives. By the nitrosation of II, N-nitroso-2-methylaminotropone was obtained in a good yield; this compound is a new type of active troponoid compound. The substitution reactions of III gave tropolonederivatives, accompanied by the hydrolysis of the
研究了 2-氨基托酮 (I)、2-甲基氨基托酮 (II) 和 2-二甲基氨基托酮 (III) 的亲电取代反应。产物的结构经水解证明可产生已知的托酚酮衍生物。通过Ⅱ的亚硝化反应,以良好的收率得到N-亚硝基-2-甲基氨基托酮;该化合物是一种新型的活性肌钙素化合物。III 的取代反应产生了托酚酮衍生物,伴随着二甲氨基的水解。然后讨论水解的机理。
