By means of a featured enamine activation, the alkylpropiolates have been successfully employed in the [3+2] annulation for the synthesis of 1,2,3‐triazoles. The synthesis of both 1,4‐ as well as the hardly available 1,5‐disubstituted1,2,3‐triazoles can be selectively accessed by using tosyl azide and tosyl hydrazine as nitrogen source, respectively.
