1,2,3-Triazoles are readily accessible in moderate to good yields by a diazo transfer reaction with I~-amino-<x,~-unsatmated ketones or esters and tosyl or mesyl azide reagent. In this methodology the nitrogen atoms N-2 and N-3 of the triazole ring are derived from diazo transfer reagent and nitroge

The diazo transfer reaction of ketones or esters (I) with mesyl azide provides a new and efficient process for the synthesis of 1,2,3-triazoles (II). Using tosyl instead of mesyl azide results in generally lower yields. -(ROMEIRO, G. A.;
