An efficient one-pot cyclization of quinoline thiosemicarbazones to quinolines derivatized with 1,3,4-thiadiazole as anticancer and anti-tubercular agents
摘要:
A series of 6,7,8-substituted thiosemicarbazones (2a-j) of 2-chloro-3-formyl-quinoline derivatives were cyclized to the title compounds (3a-j) using acetic anhydride. The structures of the final compounds (3a-j) were confirmed by elemental and spectral (IR, H-1 NMR and MS) analysis. Some of the title compounds have shown promising anticancer and antitubercular activities.
