摘要
An efficient method for the synthesis of N-alkylated 2-(4-substituted-1H-1,2,3-triazol-1-yl)-1H-indole-3-carbaldehyde has been developed starting from oxindole and indole using Huisgen's 1,3-dipolar cycloaddition reaction of organic azides to alkynes. The effect of catalysts and solvent on these reactions has been investigated. Among all these conditions, while using CuSO4 center dot 5H(2)O, DMF was found to be the best system for this reaction. It could also be prepared in a one-pot three-component manner by treating equimolar quantities of halides, azides, and alkynes. The Huisgen's 1,3-dipolar cycloaddition reaction was performed using CuSO4 center dot 5H(2)O in DMF with easy work-up procedure.
