Synthesis of 4′-[3-methyl-5-thioxo-1H-1,2,4-triazol-4(5H)-yl]-2′,5′-diphenyl-2′,4′-dihydro spiro[indolin-3,3′[1,2,4]triazol]-2-one derivatives
摘要:
In this paper 1,3-dipolar cycloaddition reaction has been studied. An efficient synthesis of 4'-[3-methyl-5-thioxo-1H-1,2,4-triazol-4(5H)-yl]-2',5'-diphenyl-2',4'-dihydro spiro(indolin-3,3'[1,2,4]triazol)-2-one derivatives using triethylamine in MeCN at room temperature is reported. The structures of the obtained compounds were confirmed by means of elemental analysis, MS and spectral (IR, H-1, and C-13 NMR) methods.
