REACTIONS OF 3,3-DIAMINOACRYLIC ACID DERIVATIVES WITH <i>o</i>-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.
