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

1,4-Disubstituted-1,2,3-triazoles were obtained in excellent yields from azides and terminal alkynes in H2O in the presence of catalytic amount of beta-cyclodextrin as a phase transfer catalyst. Also, a one-pot CuAAC reaction was carried out successfully, affording 1,4-disubstituted-1,2,3-triazoles in good to high yields starting from an alkyl bromide, sodium azide, and terminal alkyne.
