Deskripsi

A convenient and facile CuCl2·2H2O catalyzed one-pot synthetic strategy was designed for the conversion of readily available dimedone into highly functionalized N-arylhydrazinecarbothioamide based indazole derivatives. The product yields were found to be moderate to good without purification requirements. Structural features of the synthetic compounds were confirmed by various spectroscopic techniques such as 1H NMR, 13C NMR, EI-MS, FAB-MS, HREI-MS, and HRFAB-MS. The reaction intermediates were also quenched and characterized. Plausible reaction mechanisms were also discussed. Keywords: One-pot synthesis, Dimedone, Indazole, Carbothioamides
