    摘要:
    由于与反应性和选择性控制有关的困难,无环内烯烃是不对称Heck型反应中一类具有挑战性的底物。利用无环烯基醇,通过手性阴离子相转移策略发展了不对称的Heck-Matsuda反应。可以高水平的对映选择性获得各种手性酮。催化量的二甲基亚砜(DMSO)作为添加剂对于抑制氢化钯介导的副反应至关重要。

  • A highly stereoselective synthesis of Z-disubstituted olefin by O-assisted Still-Wittig rearrangement
    作者:Kazushige Fujii、Osamu Hara、Yoko Fujita、Youji Sakagami
    DOI:10.1016/0040-4039(95)02183-3
    日期:1996.1
    In the Still-Wittig rearrangement, stannylated methyl (E)-allylic ethers having an aliphatic side chain (1a-c) exhibited the usual similar stereoselectivity, although the poor stereoselectivity was remarkably improved by the assistance of an alkoxy moiety on the alkenyl chain. A stannylated methyl (Z)-allylic ether bearing an alkoxy moiety on the alkenyl chain (1e) also showed a high E selectivity
    在Still-Wittig重排中,具有脂族侧链(1a-c)的苯乙烯基甲基(E)-烯丙基醚表现出通常相似的立体选择性,尽管不良的立体选择性通过烯基链上的烷氧基部分得到了显着改善。如先前报道的,在烯基链(1e)上带有烷氧基部分的甲氧基化甲基(Z)-烯丙基醚也显示出高的E选择性。

    By the reaction with three N,N-dialkylanidosulfenyl chlorides 2 bearing representative sizes for the R group on the nitrogen atom, several substituted secondary propargylic alcohols (la-f) have been converted into the corresponding pairs of diastereoisomeric allenic sulfinamides 3a-n and 3′a-j,l.m. Their ratios have been determined by 1H NMR spectroscopy and were found to depend essentially on the
    通过与在氮原子上的R基团具有代表性尺寸的三个N,N-二烷基氨基亚磺酰氯2反应,已将几种取代的仲炔丙醇(Ia-f)转化为相应的非对映异构烯丙亚磺酰胺3a-n和3 'aj,lm。它们的比率已经通过1 H NMR光谱法确定,并且发现其比率基本上取决于起始材料的R 1和R 2基团的大小。一种纯非对映异构体3m的立体化学已通过单晶X射线分析确定。
  • Diastereo- and enantioselective synthesis of allenylcarbinols through SE2' addition of transient nonracemic propargylic stannanes to aldehydes.
    作者:James A. Marshall、Richard H. Yu、Jolyon F. Perkins
    DOI:10.1021/jo00122a040
    日期:1995.9
    The nonracemic allenylstannane 1c was prepared by S(N)2' displacement of mesylate 8 with Bu(3)-SnLi-CuBr . SMe(2). Treatment of this stannane with BuSnCl(3) followed by addition of isobutyraldehyde at -40 degrees C afforded the syn allenylcarbinol 4c in nearly 80% yield, The nonracemic aldehydes (S)- and (R)-16 were similarly converted to the adducts 17 and 18 in high yield with good to excellent diastereoselectivity. Best results were obtained when hexane was employed as the solvent, A reaction pathway is proposed to account for the steric preference of these additions, The allenylcarbinols were converted stereospecifically to the cis-2,5-dihydrofurans 23-25 upon treatment with catalytic AgNO3 in acetone.
