2-(2-Cyano-1-ethylthioethenyl)pyrroles are readily coupled (50–55°) with primary and secondary amines at the position 1 of the ethenyl moiety to eliminate ethanethiol and afford 2-(1-amino-2-cyanoethenyl)pyrroles and/or their cyclic isomers - functionalized 1-amino-3-iminopyrrolizines in good to high yields.
