3‐Amino‐4‐(anilinothiomethylidene)‐2‐cyano‐2‐pentenedioic acid diethyl ester reacts with ethylenedi‐amine, 1,3‐propylenediamine and 1,4‐butylenediamine affording bicyclic cyclocondensation products. The title compound reacts with diethylenetriamine and 2‐(2‐aminoethylamino)ethanol to give new seven membered ring tricyclic compounds. The mechanism for these reactions is discussed.
