The present paper describes a new reaction of N, N'-and N, O-linked methylene compounds with carboxylic acids such as cyanoacetic acid, malonic acid, acetoacetic acid, trichloroacetic acid and phenylpropiolic acid. By the reaction substitution of one of the linking heteroatoms of the substrates by the decarboxylated residues of the carboxylic acids is effected to proceed. The reaction presented here provides an effective means of introducing mono- and/or bis-dialkylaminomethyl grouping into the decarboxylated residue of the carboxylic acids.
本文描述了一种N,N'-和N,O-连接的亚甲基化合物与羧酸(如氰基乙酸、丙二酸、乙酰乙酸、三氯乙酸和苯丙炔酸)发生的新反应。通过反应,底物中某个连接的杂原子被羧酸的脱羧残基替代。这里介绍的反应提供了一种有效的方法,可以将单烷基或双烷基氨基甲基基团引入羧酸的脱羧残基中。
