Popis:	Nucleophilic additions of α-mercaptoalkanoate esters and β-mercaptoalkanoate acids to benzoquinone diimines, followed by cyclization with trifluoroacetic acid or 1,3-dicyclohexylcarbodiimide (DCC), provide novel, high-yielding syntheses of 2H-1,4-benzothiazin-3(4H)-ones (3a−f) and 2,3-dihydro-1,5-benzothiazepin-4(5H)-ones (5a−c), respectively.
