• One-Pot Synthesis of α-Amino Acids from CO₂ Using a Bismetal Reagent with Si–B Bond

  TsOH·H2O, precursors of N-Boc-imines can be converted into the corresponding α-aryl or α-alkenyl glycine derivatives under gaseous CO2 in moderate-to-high yields with a single operation. α-Isobutenyl glycine thus obtained can be further derivatized into various types of α-amino acids including N-Boc-leucine, serine, and glycine derivatives in short steps.

  在1.1当量的PhMe 2 Si-Bpin，5当量的CsF和20摩尔％的TsOH·H 2 O存在下，N -Boc-亚胺的前体可以转化为相应的α-芳基或α-烯基甘氨酸一次操作即可在气态CO 2下以中等至高收率得到各种衍生物。由此获得的α-异丁烯基甘氨酸可以在短时间内进一步衍生为各种类型的α-氨基酸，包括N -Boc-亮氨酸，丝氨酸和甘氨酸衍生物。

  It′s a gas: A novel one‐pot process for the synthesis of α‐amino acids from imine equivalents using CO2 gas as a carbon source has been developed. This reaction was made possible by the reagent combination of TMSSnBu3 and CsF (see scheme). Three successive reactions (imine formation, stannylation, and carboxylation) proceeded in the same flask under these conditions to give products in up to 79 % yield

  它是一种气体：已开发出一种新颖的单罐方法，该方法使用CO 2气体作为碳源，从亚胺当量合成α-氨基酸。通过TMSSnBu 3和CsF的试剂结合使该反应成为可能（参见方案）。在这些条件下，在同一烧瓶中进行了三个连续的反应（亚胺形成，甲氧基化和羧化），以最高79％的收率得到产物。Boc =叔丁氧羰基，TMS =三甲基甲硅烷基。
• Synthesis, anticonvulsant activity, and neuropathic pain-attenuating activity of N-benzyl 2-amino-2-(hetero)aromatic acetamides

  N-Benzyl 2-acetamido-2-substituted acetamides, where the 2-substituent is a (hetero) aromatic moiety, are potent anticonvulsants. We report the synthesis and whole animal pharmacological evaluation of 16 analogues where the terminal 2-acetyl group was removed to give the corresponding primary amino acid derivatives (PAADs). Conversion to the PAAD structure led to a substantial drop in seizure protection in animal tests, demonstrating the importance of the N-acetyl moiety for anticonvulsant activity. However, several of the PAADs displayed notable pain-attenuating activities in a mouse model. (C) 2012 Elsevier Ltd. All rights reserved.
• Synthesis of Arylglycine and Mandelic Acid Derivatives through Carboxylations of α-Amido and α-Acetoxy Stannanes with Carbon Dioxide
  作者：Tsuyoshi Mita、Masumi Sugawara、Hiroyuki Hasegawa、Yoshihiro Sato

  日期：2012.3.2

  Incorporation reactions of carbon dioxide (CO2) with N-Boc-alpha\-amido and a-acetoxy stannanes were developed using CsF as a mild tin activator. Monoprotected alpha-amido stannanes could be used, and the corresponding arylglycine derivatives were obtained in moderate-to-high yields under 1 MPa (10 atm) of CO2 pressure. alpha-Acetoxy stannanes also underwent carboxylation to afford mandelic acid derivatives in excellent yields under ambient CO2 pressure. Both transformations enabled the synthesis of alpha-tertiary and alpha-quaternary carboxylic acid derivatives. In addition, the chirality of (S)-N-tert-butylsulfonyl-alpha-amido stannanes was transferred with up to 90% inversion of configuration at 100 degrees C.
