  摘要：

  研究了2-乙基和2-正丙基-2-（氯甲基）-1,3-二氯丙烷与镁在四氢呋喃中的反应。这些格氏试剂的水解分别产生2-乙基-1-丁烯和2-乙基-1-戊烯作为主要产物。相同的有机镁化合物的羧化分别得到4-乙基-和4-正丙基-4-戊烯酸。这些产物与以下假设相符：反应通过烷基氯甲基环丙烷的形成和重排进行，如先前针对甲基同系物报道的1。通过常规分析和交替合成均可确定拟议化合物的身份。

• Ligand Controlled Ir-Catalyzed Regiodivergent Oxyamination of Unactivated Alkenes
  作者：Honghui Lei、John H. Conway、Caleb C. Cook、Tomislav Rovis

  DOI：10.1021/jacs.9b06366

  日期：2019.7.31

  An intramolecular Ir(III)-catalyzed regiodivergent oxyamination of unactivated alkenes provides valuable γ-lactams, γ-lactones and δ-lactams. The regioselectivity is controlled by the electronically tunable cyclopentadienyl Ir(III)-complexes enabling oxyamination via either 5-exo or 6-endo pathways. With respect to the mechanism, we propose a highly reactive [3.1.0] bicycle intermediate derived from

  未活化烯烃的分子内 Ir(III) 催化区域发散氧化胺化提供有价值的 γ-内酰胺、γ-内酯和 δ-内酰胺。区域选择性由电子可调的环戊二烯基 Ir(III)-络合物控制，该络合物能够通过 5-exo 或 6-endo 途径进行氧胺化。在机制方面，我们提出了一种源自 Ir(V) 氮烯介导的氮丙啶化的高反应性 [3.1.0] 自行车中间体，作为合成 γ-内酰胺的关键中间体。

• Total Synthesis and Evaluation of a Key Series of C5-Substituted Vinblastine Derivatives
  作者：Porino Va、Erica L. Campbell、William M. Robertson、Dale L. Boger

  DOI：10.1021/ja1027748

  日期：2010.6.23

  A remarkably concise seven- to eight-step total synthesis of a systematic series of key vinblastine derivatives is detailed and used to characterize the importance and probe the role of the C5 ethyl substituent (R = H, Me, Pr, CH=CH(2), C CH, CH(2)OH, and CHO vs Et). The analogues, which bear deep-seated structural changes accessible only by total synthesis, were prepared using a powerful intramolecular [4 + 2]/[3 + 2] cycloaddition cascade of 1,3,4-oxadiazoles ideally suited for use in the assemblage of the vindoline-derived lower subunit followed by their incorporation into the vinblastine analogues through the use of a single-step biomimetic coupling with catharanthine. The evaluation of the series revealed that the tubulin binding site surrounding this C5 substituent is exquisitely sensitive to the presence (Et > H, 10-fold), size (Me <= Et > Pr, 10-fold), shape (Et > CH=CH(2) and C CH, >4-fold), and polarity (Et > CHO > CH(2)OH, >10-20-fold) of this substituent and that on selected occasions only a C5 methyl group may provide analogues that approach the activity observed with the naturally occurring C5 ethyl group.
