Hydrazonoyl Halides Precursors to Synthesis of New Thiazole,Thiadiazole, and Benzothiazepine Derivatives
Abstract:New series of substituted thiazole and thiadiazoles were prepared starting from N ′‐(3,4‐dihydronaphthalen‐1(2H )‐ylidene)hydrazinecarbothiohydrazide by reacting with different types of hydrazonoyl chlorides. In addition, 7‐(4‐chlorophenyl)‐5,6,6a,7‐tetrahydrobenzo b ]naphtha‐1,2‐e ]1,4]thiazepine reacted with hydrazonoyl halides to afford a new derivatives of 7‐(4‐chlorophenyl)‐14‐phenyl‐5,6,6a,7‐tetrahydro‐16H‐benzob]naphtho1,2‐e]1,2,4]triazolo4,3‐d ]1,4]thiazepine. Structures of the newly synthesized compounds were elucidated on the basis of elemental analyses and spectral data.
