  Electroreductive intramolecular coupling of nonconjugated aromatic ketones

  摘要：

  The electroreduction of nonconjugated aromatic ketones gave intramolecularly coupled products. The best result was obtained using an Sn cathode in i-PrOH containing tetraalkylammonium salt as a supporting electrolyte. This reductive cyclization proceeded with remarkable stereoselectivity, and the cis isomer was obtained exclusively. A variety of new bi- and polycyclic compounds were synthesized. The reaction mechanism was studied, and it was suggested that the anion radical generated by one-electron transfer to a carbonyl group attacks an aromatic ring intramolecularly. The choice of counter cation of the anion radical was critical for the reductive cyclization. Other reductive methods employing metal reducing agents were also studied. Reduction with Na in HMPA-THF gave the same cyclized product, though the yield was lower than that with the electroreduction.

  Described are methods for preparing a deuterated aldehyde using with a photocatalyst and a hydrogen atom transfer agent in a H2O free solvent comprising D2O and an organic solvent under an inert gas. The methods may be used to convert a wide variety of aldehydes (e.g., aryl, alkyl, or alkenyl aldehydes) to C-1 deuterated aldehydes under mild reaction conditions.

  Cross‐Si‐ing the Jordan: Cross‐coupling reactions of 2‐(2‐hydroxyprop‐2‐yl)phenyl‐substituted alkylsilanes with a variety of aryl halides proceed in the presence of palladium and copper catalysts. The use of K3PO4 base allows for highly chemoselective alkyl coupling with both primary and secondary alkyl groups (Alk).

  derivatives as single diastereoisomers in most cases. The position of the substituents was also of crucial influence on the outcome; in several cases ipso-substitution leading to the formation of spiro compounds was observed. Electron-donating substituents at the aromatic moiety are less favourable for the ketyl–aryl couplings. They apparently impede the second electron transfer that is involved in this multi-step

  这项综合研究描述了芳基部分的取代基对 SmI2 介导的分子内酮基-芳基偶联反应的影响。不同取代的γ-芳基酮被用作前体，其通过4-戊烯-2-醇与相应的溴苯或碘苯的Heck反应直接制备。在用两当量的二碘化钐γ-芳基酮处理后，带有吸电子取代基，如氰基、三氟甲基或羰基，在大多数情况下，得到预期的六氢化萘衍生物，为单一的非对映异构体。取代基的位置对结果也有至关重要的影响。在一些情况下，观察到导致形成螺环化合物的 ipso 取代。芳族部分的给电子取代基对酮基-芳基偶联不太有利。它们显然阻碍了这个多步骤过程中涉及的第二次电子转移。在这些观察的基础上，详细讨论了 SmI2 促进的酮基-芳基偶联的机制。对于在间位具有吸电子取代基的前体，SmI2 促进的环化的相当稳定的碳负离子中间体可以用丙酮或烯丙基溴作为亲电试剂捕获，以区域选择性地提供相应的加成产物。我们的结果对于立体选择性生成的六氢化萘衍生物的合成应用应该是有价值的。（©

  depends on the substituents on the aryl bromide and on the base. Sterically congested and electron-rich aryl bromides gave selectively the linear ketones by migration of the double bond. With electron-poor aryl bromides, the formation of large amounts of (E)-arylalk-1-enol derivatives or side products was observed in some cases. Similar reactions rates were observed with electron-poor and electron-rich
