Abstract An improved high yielding procedure for diethyl 2,2,2-trichloroethyledine-propanedioate (3) using montinorillonite K-10 catalyst has been described. Various diethyl (substituted aminomethylene)propanedioatcs (6a-j) have been synthesised in excellent yields starting from propanedioate (3) via addition products (5a-j).
摘要 描述了使用蒙脱土 K-10 催化剂制备 2,2,2-三氯乙基丙二酸二乙酯 (3) 的改进高收率程序。从丙二酸酯 (3) 开始,通过加成产物 (5a-j),已经以极好的收率合成了各种二乙基(取代氨基亚甲基)丙二酸酯 (6a-j)。
