A simple and highly efficient method for the regioselective synthesis of isoxazolyl‐1,4‐disubstituted‐1,2,3‐triazoles 6a, 6b, 6c, 6d, 6e, 6f, 6g, 6h, 6i, 6j, 6k, 6l in good to excellent yields from terminal alkynes having isoxazole scaffold 4a, 4b, 4c and various azides through Cu(I)‐catalyzed 1,3‐dipolar cycloaddition is described. The reaction proceeds smoothly in 1:1 mixture of t‐BuOH and water
