• A Phosphetane Catalyzes Deoxygenative Condensation of α-Keto Esters and Carboxylic Acids via P^III/P^V═O Redox Cycling

  A small-ring phosphacycle is found to catalyze the deoxygenative condensation of α-keto esters and carboxylic acids. The reaction provides a chemoselective catalytic synthesis of α-acyloxy ester products with good functional group compatibility. Based on both stoichiometric and catalytic mechanistic experiments, the reaction is proposed to proceed via catalytic P(III)/P(V)═O cycling. The importance

  发现小环磷酸环可催化 α-酮酯和羧酸的脱氧缩合。该反应提供了具有良好官能团相容性的α-酰氧基酯产物的化学选择性催化合成。基于化学计量和催化机理实验，建议反应通过催化 P(III)/P(V)=O 循环进行。观察到的温度依赖性产物选择性效应证实了环应变在磷环催化剂中的重要性。结果表明，与路易斯碱（亲核）催化相反，通过 P(III)/P(V)=O 氧化还原循环操作的有机磷基催化剂的设计标准存在固有差异。

• Hydroacylation of Activated Ketones Catalyzed by <i>N</i>-Heterocyclic Carbenes
  作者：Audrey Chan、Karl A. Scheidt

  日期：2006.4.1

  N-heterocyclic carbenes derived from triazolium salts are effective catalysts between 10 and 15 mol % for the hydroacylation of activated ketones. The reducing equivalent is generated via the interaction of a nucleophilic carbene species and an aromatic aldehyde. The subsequent alcohol product can undergo an acylation event with the resulting acyl heteroazolium intermediate formed in situ between the NHC and the aldehyde. This unprecedented multiple bond-forming reaction can accommodate aromatic aldehydes as the hydride source and various electron-deficient ketones. Preliminary mechanistic evidence indicates that the reduction and acylation steps are sequential operations. The intramolecular variant of this organocatalytic reaction affords benzofuranones in good yield.
