Synthesis and Biological Activity of N-2-Perfluoroalkylethyl-substituted or Glucopyranosyl-substituted Triazole Derivatives;

To improve their bioactivities of oxadiazole and triazole analogues,a series of N-2-perfluoroalkylethyl-substituted 1,3,4-oxadiazole-2-thiones 6a～6l and 1,2,4-triazole-5-thiones 9a～9l were synthesized and their structures were confirmed by 1H NMR,19F NMR,IR,MS spectra and elemental analysis.

On the basis of these Schiff bases, a series of 1-perfluoroalkyl-substituted or glycopyranosyl-substituted 2,4-dihydro- 1,2,4-triazole-3-thione Schiff bases (5a～5r, 6a～6d) were synthesized by the reaction of the Sch.

Synthesis N-Perfluoroalkylethyl-substituted Oxadiazole, Triazole and Its Application of Quasiracemic Synthesis;

A new convenient synthesis of a series of polyfluoroalkyl substituted cyclopropane derivatives was achieved by the reaction of polyfluoroalkyl iodides with diethyl allylmalonate in the presence of sodium dithionite in 45%～55% yields.
