英文摘要: A series of 5-fluoroalkylated IH-I,2,3-triazoles were synthesized in good yield by the regiospecific l,3-dipolar cycloaddition reaction of (Z)-ethyl 3-fluoroalkyl-3-pymolidino-acrylates with aryl or benzyl azides. In the cases of benzyl azides, addition of NazCO3 vcmcial for a high yield of the triazoles. Tetrakis(dimethylamino)ethylene (TDAE) promoted reaction of bromodifiuoro-medlylated Riazl widl aldehydes affording a new class of β,β-difiuoro-β-triazolyl alcohol derivatives, which were lactonized with catalytic amount P-toluenesuronic acid in toluene at 80-90℃C to give a series of novel bicyclic gem-difiuorinated IH-pyrano[3,4-d][1,2,3]-triazol-4-one compounds in good yield.
