    Enantioselective Synthesis of α-Amino Acids from N-Tosyloxy β-Lactams Derived from β-Keto Esters
    摘要:
    A novel synthetic sequence has been developed to convert simple beta-keto esters into enantiomerically enriched alpha-amino acids. The key features of this sequence include the addition of azide to the C3 position of beta-keto ester derived N-tosyloxy-beta-lactams through a concomitant nucleophilic addition/ N-O bond reduction reaction, a mild CsF-induced N1 benzylation of a-azido monocyclic beta-lactams, the preparation of alpha-keto-beta-lactams through a novel four-step sequence from the corresponding 3-azido-1-benzyl-beta-lactams, and TEMPO-mediated ring expansion of these compounds to the corresponding N-carboxy anhydrides (NCAs). In addition, the synthesis, isolation, and characterization of unusual 3-imino and 3-chloramino-beta-lactams is reported.

    摘要:
    酒石酸改性的Raney镍(TA-MRNi)是一种手性非均相催化剂,用于前手性酮的氢化反应。以乙酰乙酸甲酯(1)为底物,光学收率(OY)为86%,当采用在γ位置具有适当体积的β-酮酯时,OY提高至94-96%。γ体积效应有助于TA-MRNi催化剂具有高固有的手性区分能力(因子-i)。通过研究,我们发现最佳底物,即γ-环丙基-β-酮酯,其氢化反应的光学收率达到了98.6%。这一光学收率的进一步提升归因于底物特定的手性修饰剂激活手性区分氢化反应,从而减少了非手性区分氢化(N-位点催化)的贡献。通过与表现良好的β-酮酯进行比较,分析了1氢化反应的OY,并评估了因子-i和N-位点对OY值的贡献,从而推导出手性区分的起源。

  • Selective Transfer Hydrogenation of Carbonyl Compounds by Ruthenium Nanoclusters Supported on Alkali-Exchanged Zeolite Beta
    作者:M. Lakshmi Kantam、B. Purna Chandra Rao、B. M. Choudary、B. Sreedhar
    DOI:10.1002/adsc.200505497
    日期:2006.9
    Selective transfer hydrogenation of aromatic ketones and β-keto esters to the corresponding alcohols was achieved by using ruthenium nanoclusters supported on alkali-exchanged zeolite beta catalyst. The high activity and selectivity of the catalyst is due to the presence of highly dispersed ruthenium clusters in combination with the large number of Brønsted acidic sites of zeolite.
    通过使用负载在碱交换沸石β催化剂上的纳米团簇,实现了芳香族酮和β-酮​​酸酯向相应醇的选择性转移氢化。催化剂的高活性和选择性归因于高度分散的簇与大量布朗斯台德酸性位点的结合。
