  • SN2′ selective alkylation of allylic chlorides and mesylates with RZnX reagents generated from Grignard reagents, zinc chloride, lithium chloride, and Cu(II)-salts
    作者:Nobutaka Fujii、Kazuo Nakai、Hiromu Habashita、Hidenori Yoshizawa、Toshiro Ibuka、Fabrice Garrido、André Mann、Yukiyasu Chounan、Yoshinori Yamamoto
    DOI:10.1016/s0040-4039(00)60534-8
    日期:1993.6
    Treatment of RMgX (1 equiv. R = alkyl; X = Cl, Br) with ZnCl2 (1 equiv.) in a mixed solvent of THF and Et2O leads to a highly turbid white suspension. Addition of LiCl (1∼2 equiv.) solubilizes the insoluble species to yield a colorless clear solution. Addition of a catalytic amount of a Cu(II)-salt followed by allylic halides or mesylates at 0 °C ∼ room temperature yielded SN2′products in high yields
    在THF和Et 2 O的混合溶剂中用ZnCl 2(1当量)处理RMgX(1当量R =烷基; X = Cl,Br),会导致高度混浊的白色悬浮液。加入LiCl(1〜2当量)可溶解不溶物,得到无色澄清溶液。在0°C到室温下,加入催化量的Cu(II)盐,然后加入烯丙基卤化物或甲磺酸酯,可以高收率得到S N 2 '产物。还报道了合成(E)-烯烃二肽等排体的应用。
  • Remarkable difference in reactivity of ordinary vinylcopper reagents and vinylzinc halide containing a copper salt towards γ-mesyloxy-α, β-enoates. Synthesis of homochiral 1,4-dienes

    日期:——
    Whereas the reaction of gamma-mesyloxy alpha,beta-enoates with vinyl-Cu(CN)M or (vinyl)2Cu(CN)M2 (M = Li or MgX) yielded a reduction product with an (E)-double bond at the beta,gamma-position, treatment of the same substrates with ''higher order'' zinc cuprate reagents or vinyl-ZnCl by the addition of catalytic amount of Cu(I) or Cu(II) salt afforded alpha- and gamma-vinylation products. Both vinylation products were stable 1,4-diene derivatives that are only more difficulty accessed by more traditional means.
  • “Higher order” zinc cuprates involving lithium chloride: Synthesis of (E)-alkene dipeptide isosteres free from reductive elimination products

    日期:1992.6
    The “higher order” organozinc cuprates, R2Cu(CN)(ZnCl)2·2Mg(X)Cl·nLiCl, derived from admixture of LiCl (1∼2 equiv.), ZnCl2 (1 equiv.), RMgX (1 equiv.), and CuCN (0.5 equiv.) in a mixed solvent of THF and Et2O exhibit high diastereoselection of up to > 99: 1 in the synthesis of (E)-alkene dipeptide isosteres from γ-mesyloxy-α,β-unsaturated esters. Addition of lithium chloride is essential for the preparation
