    摘要:
    我们报告了连续 C(sp 2 )–C(sp 3 ) Suzuki 交叉偶联不对称氢化策略的开发,该策略允许获得多种有价值的 β,β-二取代丙氨酸衍生物。该合成表现出广泛的官能团耐受性,并可以有效地获得β-芳基-β-烷基和更罕见报道的β,β-二烷基Ala衍生物,具有高产率和优异的对映选择性。这种转化已在十克数量上得到展示,并且可用于生成可用于 SPPS 的 Fmoc 氨基酸衍生物。

    摘要:
    The Wittig-Horner reaction of CbzNHCH(CO(2)Me)P(O)(OMe)(2) (1) with ArCHO (2) in the presence of Et(3)N as a base affords methyl (Z)-3-aryl-2-(carbobenzoxyamino)acrylate (3) with high degrees of diastereoselectivity (Z)/(E) > 10:1. One recrystallization of the crude product is sufficient to obtain isomerically and chemically pure (Z)-3.

  • Carbohydrate Phosphinites as Practical Ligands in Asymmetric Catalysis:  Electronic Effects and Dependence of Backbone Chirality in Rh-Catalyzed Asymmetric Hydrogenations. Synthesis of <i>R</i>- or <i>S</i>-Amino Acids Using Natural Sugars as Ligand Precursors
    作者:T. V. RajanBabu、Timothy A. Ayers、Gary A. Halliday、Kimberly K. You、Joseph C. Calabrese
    DOI:10.1021/jo970884d
    日期:1997.8.1
    Vicinal diarylphosphinites derived from carbohydrates are excellent ligands for the Rh(I)-catalyzed enantioselective asymmetric hydrogenation of dehydroamino acid derivatives, producing the highest enantioselectivity of any ligands directly prepared from natural products. The enantioselectivity can be enhanced by the appropriate choice of substituents on the aromatic rings of the phosphinites. For example, the use of phosphinites with electron-donating bis(3,5-dimethylphenyl) groups on phosphorus provides ee's up to 99% for a wide range of amino acids including some with easily removable N-protecting groups. Electron-withdrawing aryl substituents, on the other hand, decrease the enantioselectivity. Sense of chiral induction in the amino acid product depends on the relative juxtaposition of the vicinal diphosphinites on a given sugar backbone. When readily available D-glucopyranosides are used as the starting sugars, 2,3-phosphinites give the S-amino acids and 3,4-phosphinites give the R-amino acids. In the case of aromatic and heteroaromatic amino acids, enantioselectivities > 95% are consistently obtained. Practical considerations such as the ease of ligand synthesis, rates of reactions, catalyst turnover, and scope and limitations in terms of substrates are discussed. A possible explanation for the enhancement of enantioselectivity by electron-rich phosphinites is offered.
