  季碳全碳立体中心催化对映选择性合成3,4-多羟基吲哚：Rh催化的CC活化方法

  摘要：

  据报道，第一个Rh催化的3,4-polyfused oxindole环系统的对映选择性合成是通过基于CC活化的丙烯酸酰胺的碳酰化实现的。这种转变为进入带有四级立体中心的3,4-多聚羟吲哚提供了新的机会。三到五环的3,4-稠合的吲哚以不对称的产率（高达95％）产生，并具有良好或优异的对映选择性（88％–97％ee）。分六个步骤完成了对木苯二酚A的第一次总合成的应用，总产率为14％。

  DOI：10.1039/c6ra28744a

  日期：——

  Cooperative photoredox and cobalt catalyzed carboxylation of styrenes with CBr4 to afford the corresponding α,β-unsaturated carboxylic acids has been realized through radical addition and Kornblum (DMSO) oxidation. DMSO serves as the oxidant, oxygen source and solvent under these photocatalytic conditions.

• Photochemical Synthesis of Highly Functionalized Cyclopropyl Ketones
  作者：Pablo Wessig、Olaf Mühling

  DOI：10.1002/hlca.200390086

  日期：2003.3

  trisubstituted cyclopropyl ketones 11 were prepared by irradiation of ketones 3 and 5, which bear a leaving group adjacent to the carbonyl C-atom. The required ketones 3 could be easily synthesized either by functionalization of ketones 1 with a hypervalent iodine reagent, 2, or by O-sulfonylation of α-hydroxy ketones 7. The nitrates 5 were obtained by treatment of the corresponding α-bromo ketones with AgNO3

  通过辐射酮3和5制备一系列二和三取代的环丙基酮11，所述酮3和5带有与羰基C-原子相邻的离去基团。所需的酮3可以通过使用高价碘试剂2对酮1进行功能化或通过α-羟基酮7的O-磺酰化来轻松合成。通过用AgNO 3处理相应的α-溴代酮获得硝酸盐5。3和5的照射必须在除酸剂（1-甲基-1 H-咪唑）的存在下进行，以获得高收率的环丙烷11。除其他事项外，该方法的合成效率通过制备高收率的高应变双环[2.1.0]戊烷11i得以证明。通过光动力学测量以及量子化学计算研究了光化学环化的机理。已经表明，离去基团的存在实质上影响了光化学反应级联的所有步骤。还确定了11j和exo - 11k的X射线晶体结构。

  日期：2021.10.1

  A ruthenium-catalyzed synthetic method for branched allylic esters via addition of carboxylic acids to allenes is reported. Ligands were designed and prepared based on the Josiphos skeleton, with which the reaction achieved up to 95% yield and up to >99% enantiomeric excess. A deuterium labeling experiment was performed and a plausible mechanism was proposed. Enantiopure lactones of five- and six-membered
