摘要：

1,2,3-Triazoles are readily accessible in moderate to good yields by a diazo transfer reaction with beta-amino-alpha,beta-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.
