Abstract

2-Ethynyl-4,5,6,7-tetrahydroindoles, readily available from 4,5,6,7-tetrahydroindoles and bromoacetylenes on K2CO3, when treated with sodium azide in DMSO, afford functionalized tetrahydroindole-triazoles ensembles. The reaction proceeds under mild conditions (room temperature) to give triazoles with acyl or ester­ moieties in quantitative yields.
