Abstract
magnified image Reaction of diacyl thiocarbohydrazides with dimethyl but‐2‐ynedioate in refluxing ethanol led to 4‐oxa‐thiazolidine‐5‐ylidene‐acetates in good yields. Reaction of the newly prepared N‐(2‐(propan‐2‐ylidene) hydrazine‐carbonothioyl)arylhydrazides with dimethyl but‐2‐ynedioate gave the corresponding (Z)‐methyl‐2‐arylhydrazide‐4‐oxo‐3‐(propan‐2‐ylideneamino)thiazolidine‐5‐ylidene)‐acetates. The mechanism is discussed. Antitumor and antioxidant activities have been also investigated. J. Heterocyclic Chem., (2010).
