Abstract

(Z)‐N^1^‐(2‐Amino‐1,2‐dicyanovinyl)‐N^2^‐substituted‐formainidines react with dimethylformamide diethyl acetal at room temperature to give 6‐cyanopurines as the major product together with novel 5‐amino‐2‐arylimino‐3,4‐di[(N,N‐dimethylamino)methylideneamino]‐2__H__‐pyrroles, which have been fully characterised and a single crystal X‐ray analysis has been carried out on the N‐phenyl derivative.
