Abstract
1, 2, 3-Triazoles are readily accessible in moderate to good yields by a diazo transfer reaction with β-amino-α, β-unsaturated 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 nitrogen atom N-1 is derived from the appropriate enamine.
