✦ Synopsis

Cyclopentadienones react with EtO 2 CN S O and related N S reagents to provide ready syntheses of 1,2,5-thiadiazolidines (8, 12, 17), diaminosulfanes (11, 13), an aminocyclopentenone (10) and the first unoxidised 1,2,3-oxathiazolidine ( ), all in a mechanistically rational manner.

Enantiopure 1,4-benzodiazepin-4-one 1 and 1,4-benzodiazepin-6-ones 2 were reacted with hydrazonoyl chloride 8 in the presence of various basic agents. The diastereoselective 1,3-dipolar cycloaddition between the C N double bond of 1 or 2 and the nitrilimine intermediate 9 gave the enantiopure [1,2,4

## Abstract The azomethine imine group of isoquinolinium __N__‐arylimides 2 is partially incorporated into an aromatic ring. The nucleophilic‐electrophilic 1,3‐dipoles 2 undergo cycloadditions to ethylene derivatives bearing either electron‐withdrawing or electron‐releasing substituents. The regioc
