A facile method for solid‐phase organic synthesis of 1‐substituted‐4‐vinyl‐1,2,3‐triazoles from polystyrene‐supported but‐3‐ynyl selenide has been developed. This sequential [3+2] cycloaddition and oxidation–elimination reactions could be carried out under mild reaction conditions with straightforward operation and good yield and purity of the products, and broad scope of substrates, and could be...
A novel Wang resin‐bound 2,3‐dibromopropionate reagent has been developed and used as a potential dipolarophile for the facile preparation of methyl 3‐substituted‐isoxazole‐5‐carboxylates through triethylamine, promoting a sequence of reactions involving the in situ generation of 2‐bromoacrylate resin and nitrile oxide, regioselective 1,3‐dipolar cycloaddition, and loss of hydrogen bromide in one...
