Interaction of heterothiocumulenes with 2-amino-3-cyanothiophenes: Formation of thienopyrimidines

Thieno-fused(1,3)-thiazine, 4-imino-2-thioxo-2,4-dihydro-1H-thieno(1,3)-thiazine (2) has been directly synthesised by the reaction of o-aminonitrile (1a) with carbon disulphide.Thiazine (2) on reaction with primary aromatic amines leads to thieno2
