2-Imino-3-(o-aminoaryl)-4-thiazolines (II) gave thiazolo-benzotriazepines(I) on condensation with variousaliphatic carboxylic acids. Both N-acyl(III) and N,N′-diacyl derivatives(IV) were isolated, and the monoacyl derivatives (III) were also cyclized to thiazolo-benzo-triazepines.

Some new 7-substituted
3-phenyl-1H-imidazo[1,2-a]benzimidazoles have been synthesized by the thermal
rearrangement of 3-(o-amino-substituted phenyl)-2-imino-4-phenyl-4-thiazoline.
A mechanism of formation of the products is suggested.
