  • A Catalytic Michael/Horner-Wadsworth-Emmons Cascade Reaction for Enantioselective Synthesis of Thiochromenes
    作者:Abhijnan Ray Choudhury、Santanu Mukherjee
    DOI:10.1002/adsc.201300281
    日期:2013.7.8
    A catalytic enantioselective sulfa‐Michael/Horner–Wadsworth–Emmons reaction cascade has been developed, taking advantage of phosphonate as an electrophilic activator and a traceless binding site. Using a chiral bifunctional urea derivative as the catalyst, a variety of aryl and heteroaryl substituted thiochromenes was obtained in excellent yield with a high level of enantioselectivity.
    利用膦酸酯作为亲电子活化剂和无痕结合位点,已开发出催化对映选择性磺胺-Michael / Horner-Wadsworth-Emmons反应级联反应。使用手性双官能脲衍生物作为催化剂,以优异的收率和高的对映选择性获得了各种芳基和杂芳基取代的硫代色素。

  • Mg-Promoted Regioselective Carbon-Silylation of α-Phosphorylacrylate Derivatives
    作者:Makoto Kyoda、Takamichi Yokoyama、Takeshi Kuwahara、Hirofumi Maekawa、Ikuzo Nishiguchi
    DOI:10.1246/cl.2002.228
    日期:2002.2
    Treatment of aromatic α-phosphorylacrylate derivatives 1a-h with Mg turnings in the presence of trimethylsilyl chloride brought about facile and regioselective C-silylation to give the corresponding β-silylated phosphonates 2a-h in excellent yields. The reaction took place smoothly for activated olefins possessing appropriate reduction potentials and may be initiated by electron transfer from Mg to 1a-h.
