  Structure–activity relationships of the peptide deformylase inhibitor BB-3497: modification of the P2′ and P3′ side chains

  摘要：

  Structural modifications to the peptide deformylase inhibitor BB-3497 are described. In this paper, we describe the initial SAR around this lead for modifications to both the P2' and P3' side chains. Enzyme inhibition and antibacterial activity data revealed that a variety of substituents are tolerated at the P2' and P3' positions of the inhibitor backbone. The data from this study highlights the potential for modification at the P2' and P3' positions to optimise the physicochemical properties. (C) 2003 Elsevier Ltd. All rights reserved.

• Highly Enantioselective Synthesis of N‐Unprotected Unnatural α‐Amino Acid Derivatives by Ruthenium‐Catalyzed Direct Asymmetric Reductive Amination
  作者：Le'an Hu、Yuan‐Zheng Wang、Lei Xu、Qin Yin、Xumu Zhang

  DOI：10.1002/anie.202202552

  日期：2022.6.20

  An unprecedented Ru-catalyzed direct asymmetric reductive amination of α-keto amides with ammonium salts has been achieved. This protocol provides an efficient and practical way for the synthesis of diverse enantioenriched α-aryl- or alkyl-substituted N-unprotected unnatural α-amino acids and N-unprotected β-branched α-amino acids. Further follow-up transformations enable access to drug intermediates

  已经实现了前所未有的Ru催化的α-酮酰胺与铵盐的直接不对称还原胺化。该协议为合成多种对映体丰富的α-芳基或烷基取代的 N-未保护的非天然 α-氨基酸和 N-未保护的 β-支链 α-氨基酸提供了一种有效且实用的方法。进一步的后续转化能够获得药物中间体、肽和有机催化剂/配体。
• Total Synthesis of (−)-Antroalbocin A Enabled by a Strain Release-Controlled Photochemical 1,3-Acyl Shift

  The first bioinspired, enantioselective, and protecting group free total synthesis of the antibacterial sesquiterpenoid (−)-antroalbocin A (1) has been achieved in 12 steps (5.4% overall yield) from dimedone. An organocatalytic Robinson annulation gave rapid access to the tricyclic enone (19) as starting material for the photochemical domino process of deconjugation and sigmatropic 1,3-acyl shift.

  抗菌倍半萜类化合物 (-)-antroalbocin A ( 1 ) 的第一个生物启发、对映选择性和无保护基团的全合成已经从二甲酮通过 12 个步骤（总产率 5.4%）实现。有机催化的 Robinson 环化可以快速获得三环烯酮 ( 19 ) 作为去共轭和 sigmatropic 1,3-酰基转移的光化学多米诺过程的起始材料。该过程的计算数据表明，1,3-酰基转移受益于高度应变的 1,3-烯酮8。8向其桥接异构体5的转变是放能的，因此与未应变的底物相比，能够提高转化率。
