                                    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.
