  铑酰胺基络合物在水介质中催化α，β-不饱和酮的化学选择性共轭还原

  摘要：

  尽管Noyori Ru-TsDPEN配合物的显着特征是转移氢化反应对C═O官能团具有高度的化学选择性并且对烯烃具有耐受性，但我们的早期报告表明，化学选择性可以从C═O切换为C═C键在活化的α，β-不饱和酮的转移氢化中。现在我们发现，即使在没有其他吸电子官能团的情况下，也可以在水性介质中使用酰胺-铑氢化物络合物以高选择性将各种α，β-不饱和酮还原成烯烃双键，并且具有很高的选择性。已经实现了化学选择性。值得注意的是，从有机溶剂到水，化学选择性显着提高。此外，1

  Synthesis of a-Alkylated Ketones via Tandem Acceptorless Dehydrogenation/a-Alkylation from Secondary and Primary Alcohols Catalyzed by Metal–Ligand Bifunctional Iridium Complex [Cp*Ir(2,2′-bpyO)(H₂O)]

  摘要：

  A new strategy for the synthesis of alpha-alkylated ketones via tandem acceptorless dehydrogenation/alpha-alkylation from secondary and primary alcohols was proposed and accomplished. In the presence of metal-ligand bifunctional iridium complex [Cp*Ir(2,2'-bpyO)(H2O)], various desirable products were obtained in high yields. Compared with previous methods for the direct dehydrogenative coupling of secondary alcohols with primary alcohols to alpha-alkylated ketones, this protocol has obvious advantages including complete selectivity for alpha-alkylated ketones and more environmentally benign conditions. Notably, the study also exhibited the potential to develop tandem reactions catalyzed using a metal-ligand bifunctional iridium complex.

• Copper-Catalyzed Synthesis of Esters from Ketones. Alkyl Group as a Leaving Group
  作者：Yuji Nakatani、Yuichiro Koizumi、Ryu Yamasaki、Shinichi Saito

  DOI：10.1021/ol800576w

  日期：2008.5.1

  The conversion of ketones to esters has been achieved through the use of Cu catalyst and tetrabutylammonium nitrite. This reaction involves the activation of the less activated C-C bond, and the alkyl group is removed as a leaving group. Various isopropyl ketones are found to be good substrates for this reaction.

  one-carbon homologation of carbonyl compounds is described. The method is based on the rearrangement of β-oxido carbenoid which is generated via the ligand exchange reaction of the sulfinyl group of α-chloro β-hydroxy sulfoxide with tert-butyllithium. Addition of the carbanion of aryl 1-chloroalkyl sulfoxides to carbonyl compounds gave the adducts in good yields. The β-oxido carbenoid rearrangement of the

  The rhodium‐catalyzed methylation of ketones has been accomplished using methanol as the methylating agent and the hydrogen‐borrowing method. The sequence is notable for the relatively low temperatures that are required and for the ability of the reaction system to form α‐branched products with ease. Doubly alkylated ketones can be prepared from methyl ketones and two different alcohols by using a

  Herein we report the palladium-catalyzed isomerization of highly substituted allylic alcohols and alkenyl alcohols by means of a single catalytic system. The operationally simple reaction protocol is applicable to a broad range of substrates and displays a wide functional group tolerance, and the products are usually isolated in high chemical yield.

  在此，我们报告了通过单一催化体系钯催化的高度取代的烯丙醇和链烯醇的异构化。操作简单的反应方案适用于广泛的底物，并显示出广泛的官能团耐受性，并且产物通常以高化学产率分离。实验和计算机制研究为由重复迁移插入/β-H 消除序列组成的链行走过程提供了补充和收敛的证据。有趣的是，在烯丙醇异构化过程中，催化剂不会从底物上解离，而当烷基链上存在额外的取代基时，它会在烯醇异构化过程中脱离。
