  • Enantioselective catalysis of carbonyl-ene and Friedel–Crafts reactions with trifluoropyruvate by ‘naked’ palladium(II) complexes with SEGPHOS ligands

    enantioselectivity not only in carbonyl-ene but also in Friedel–Crafts reactions stem from the effective shielding with diphenyl groups on phosphines caused by the narrow dihedral angle of metal complexes with SEGPHOS.

    An efficient asymmetric carbonyl-ene reaction of trifluoropyruvate catalyzed by chiral Pd(II)/(S)-SunPhos complex was developed. A series of optically active homoallylic alcohols containing a CF3 group were obtained with high yields and excellent ee under mild conditions. Particularly, the reaction of isobutylene and trifluoropyruvate gave the desired product (90% yield, 98% ee) with catalyst loading

  • Asymmetric catalysis of ene reactions with trifluoropyruvate catalyzed by dicationic palladium(II) complexes
    作者:Kohsuke Aikawa、Satoshi Kainuma、Manabu Hatano、Koichi Mikami
    DOI:10.1016/j.tetlet.2003.10.137
    日期:2004.1
    Chiral dicationic SEGPHOS-Pd(II) complex achieves a high chemical yield, (E)-olefin selectivity, anti-diastereoselectivity, along with high enantioselectivity even with less reactive mono- and 1,2-disubstituted olefins in this much less reactive ketoneene reactions. The high levels of enantio selectivity stem from the effective shielding with diphenyl groups on phosphines caused by the narrow dihedral angle of metal complexes with SEGPHOS. (C) 2003 Elsevier Ltd.

  • Tandem ionic liquid antimicrobial toxicity and asymmetric catalysis study: carbonyl-ene reactions with trifluoropyruvate
    作者:Rohitkumar G. Gore、Thi-Kim-Thu Truong、Milan Pour、Lauren Myles、Stephen J. Connon、Nicholas Gathergood
    DOI:10.1039/c3gc40875b
    日期:——
    The asymmetric carbonyl-ene reaction of trifluoropyruvate with five alkenes catalysed by [Pd(R)-BINAP}](SbF6)2 were carried out in good yields and enantioselectivities (up to 96% yield and 96% ee) in low antimicrobial toxicity C2-substituted imidazolium ionic liquids (ILs). Toxicity data was included in the selection criteria for reaction optimisation after a preliminary IL screen. The Pd(II) catalyst immobilised in an IL was recycled and reused up to 7 times without decrease of either yield or ee. One IL prepared, which was determined to be of high antimicrobial toxicity was assigned a low priority for future applications.
    在低抗菌毒性的C2取代咪唑鎓离子液体(ILs)中,三氟丙酮酸与五种烯烃的非对称羰基-烯反应在[Pd(R)-BINAP}](SbF6)2催化下,实现了良好的产率和立体选择性(最高达96%产率和96% ee)。在初步的IL筛选后,毒性数据被纳入反应优化的选择标准。固定在IL中的Pd(II)催化剂可回收并重复使用多达7次,且产率和ee均无下降。一种制备的IL被确定具有高抗菌毒性,因此被赋予低优先级用于未来的应用。
