1-Imino-3-(4-imino-5-thiazolidinylidene)isoindolines

A compound of the formula ##STR43## wherein:

• A is a divalent radical combining with the --C.dbd.C-- portion of the molecule to which it is attached to form a six-membered carbocyclic ring and is selected from the group consisting of ##STR44## where in each instance C(7) and C(4) are bonded to C(7a) and C(3a) respectively, and in which R, R.sub.1, R.sub.2 and R.sub.3 are the sam or different and are selected from the class consisting of hydrogen, alkyl having one to three carbon atoms, alkoxy having one to three carbon atoms, halo, trifluoromethyl, phenyl and phenyl substituted by alkyl having one to three carbon atoms, alkoxy having one to three carbon atoms and halogen;
• and
• Y is a divalent radical combining with the --S--C--C-- portion of the molecule to form a five-membered heterocyclic ring having the same orientation as a thiazole ring and is ##STR45## in which N.dbd.B is di-lower-alkylamino, piperidino, pyrrolidino, morpholino, (lower-alkyl)-(phenyl)-amino or (lower-alkyl)-(phenyl-lower-alkyl)amino.
