The interaction of the ethyl ester or pyrrolidide of 3,3-diaminoacrylic acid with aromatic and heteroaromatic nitriles containing a labile halogen atom in the ortho position, leads to the formation of products of its substitution by the α-carbon atom of the diaminoacrylic acid derivative. The compounds obtained are cyclized smoothly into fused diaminoazines.
3,3-二氨基丙烯酸的乙酯或吡咯化物与在邻位含有不稳定卤素原子的芳族和杂芳族腈的相互作用导致形成其被二氨基丙烯酸衍生物的α-碳原子取代的产物。将获得的化合物平稳地环化成稠合的二氨基嗪。
