  Structure–activity relationships of the peptide deformylase inhibitor BB-3497: modification of the methylene spacer and the P1′ side chain

  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 the methylene spacer and the P1' side chain. Enzyme inhibition and antibacterial activity data revealed that the optimum distance between the N-formyl hydroxylamine metal binding group and the P1' side chain is one unsubstituted methylene unit. Additionally, lipophilic P1' side chains that closely mimic the methionine residue in the substrate provided compounds with the best microbiological profile. (C) 2003 Elsevier Ltd.

• Electrochemical Tandem Olefination and Hydrogenation Reaction with Ammonia

  Horner–Wadsworth–Emmons/hydrogenation tandem reaction was achieved using ammonia as electron and proton donors. The reaction could give two-carbon-elongated ester and nitrile from aldehyde or ketones directly. This reaction could proceed with a catalytic amount of base or even without a base. The ammonia provides both the electron and proton for this tandem reaction and enables the catalyst-free hydrogenation

  使用氨作为电子和质子供体实现了电化学 Horner-Wadsworth-Emmons/氢化串联反应。该反应可以直接由醛或酮得到双碳延伸的酯和腈。该反应可以在催化量的碱或什至没有碱的情况下进行。氨为该串联反应提供电子和质子，并使 α,β-不饱和 HWE 中间体的无催化剂氢化成为可能。报告了 40 多个例子，并且可以容忍包括杂环和羟基在内的官能团。

  (0.5 V vs SCE) and that a proposed protodemetalation mechanism offers a broad scope of electron-deficient olefins, offering high diastereoselectivity in the case of endocyclic alkenes. The coupling of chlorine radical generation with Cu reduction through LMCT enables the generation of a highly active HAT reagent in an operationally simple and atom economical protocol.

  我们利用催化 CuCl 2报告了通过未活化的 C(sp 3 )-H 键与缺电子烯烃的偶联对许多原料化学品的功能化。活性铜酸盐催化剂经历配体到金属电荷转移 (LMCT) 以产生氯自由基，该氯自由基充当强大的氢原子转移试剂，能够提取强富电子 C(sp 3)–H 键。值得注意的是，氯铜酸盐催化剂是一种非常温和的氧化剂（0.5 V vs SCE），并且提出的原型脱金属机制提供了广泛的缺电子烯烃，在环烯烃的情况下提供了高非对映选择性。通过 LMCT 将氯自由基生成与 Cu 还原相结合，能够以操作简单且原子经济的方案生成高活性 HAT 试剂。
