Fused thiazolidine 11 and thiazoline derivatives Ha-c are obtained by intramolecular cycloaddition-elimination reactions of appropriately substituted Mninothiatriazolines 10 and Ha-c. The incorporation of a sidechain phenyl group excercises a favorable effect on cycllxation since no reaction is obse
