The reaction of o-phenylenediamine (4) with one, two or three equivalents of p-substituted 3-dimethylaminopropiophenone hydrochlorides 5a−e was studied. 4-Aryl-2,3-dihydro-1H-1,5-benzodiazepine derivatives 6a−e were obtained in good yields, along with the 1:2-adducts 7c−e and the unexpected 1:3-adducts rac-8c−e. The type of adduct formed is determined by the molar ratio of the reactants 4 and 5 and
研究了邻苯二胺 (4) 与一、二或三当量的对取代的 3-二甲氨基苯丙酮盐酸盐 5a-e 的反应。4-Aryl-2,3-dihydro-1H-1,5-benzodiazepine 衍生物 6a-e 与 1:2-加合物 7c-e 和意外的 1:3-加合物 rac-8c-一起以良好的产率获得e. 形成的加合物的类型由反应物 4 和 5 的摩尔比以及苯丙酮 5 的对位取代基的性质决定。
