A copper(I)-mediated tandem three-component reaction using alkynes, azides, allyl
iodides, CuI and NaNH2 is developed. The reactions proceed smoothly at room temperature to afford 5-allyl-1,2,3-triazoles,
which can be further converted into 1,2,3-triazole-fused tricyclic scaffolds. This
method features an efficient one-pot cascade route using commercial alkynes and affords
the corresponding 5-allyl-1,2,3-triazoles with high yields and good selectivity under
mild reaction conditions.
