Synthesis of phenyl azides bearing (E)-2-halovinyl group
Aseries of phenyl azides bearing (E)-2-halovinyl groups were synthesized in high yields by treatment of (E)-3-(4-azidophenyl)- and (E)-3-(2-azidophenyl) acrylic acid with N-halosuccinimide in the presence of LiOAc. (E)-4-(2-bromovinyl) phenyl azide, one o

Stereoselective synthesis of phenyl-1,2,3-triazoles containing (E)-vinyl halide group via a one-pot, three-component reaction
Phenyl-1,2,3-triazoles containing (E)-vinyl halide were readily synthesized via a one-pot, three-component reaction of 3-(4- or 2-azidophenyl)acrylic acid, NXS(X=Cl, Br and I) and 1-alkynes in MeCN-H2O (9:1v/v) catalyzed by LiOAc/CuI-sodium ascorbate syst
Synthesis of phenylazides and 1-phenyl-1,2,3-triazoles bearing (E)-2-halovinyl group
Treatment of (E)-3-(4-azidophenyl)and (E)-3-(2-azidophenyl)acrylic acid with N-halosuccinimides in the presence of LiOAc afforded high yields of phenylazides containing (E)-2-halovinyl group. The latter were transformed to different phenyl-1,2,3-triazoles
