REACTIONS OF 3,3-DIAMINOACRYLIC ACID DERIVATIVES WITH o -HALOARENECARBONITRILES. SYNTHESIS OF FUSED AZINES

Abstract

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. Authors: E. M. Igumnova, S. I. Selivanov, D. V. Dar'in, and P. S. Lobanov.
