    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。

  • Over 98% Optical Yield Achieved by a Heterogeneous Catalysis. Substrate Design and Analysis of Enantio-Differentiating Factors of Tartaric Acid-Modified Raney Nickel Hydrogenation

    Tartaric acid-modified Raney nickel (TA-MRNi) is a chiral heterogeneous catalyst for the hydrogenation of prochiral ketones. An optical yield (OY) of 86% with methyl acetoacetate (1) as a substrate was improved to 94–96% by employing β-keto esters having a proper bulkiness at the γ -position. The γ -bulkiness effect contributes to a high intrinsic enantio-differentiating ability (factor-i) of the TA-MRNi catalysis. Through the study, we found the best substrate, γ -cyclopropyl-β-keto ester, the hydrogenation of which resulted in 98.6% OY. This further improvement in the OY was ascribed to a smaller contribution of non-enantio-differentiating hydrogenation (N-site catalysis) due to the substrate-specific activation of the enantio-differentiating hydrogenation by the chiral modifier. The OY of the hydrogenation of 1 was analyzed by comparing with well-behaved β-keto esters, and the contribution of the factor-i and the N-site to the OY value was evaluated to deduce the origin of the enantiodifferentiation.
