• A Practical Synthesis of β-Keto Thioesters by Direct Crossed-Claisen Coupling of Thioesters and N-Acylbenzotriazoles
  作者：Don Coltart、Guoqiang Zhou、Daniel Lim、Fang Fang

  日期：2009.10

  Thioesters undergo chemoselective soft enolization and acylation with N-acylbenzotriazoles on treatment with MgBr2˙OEt2 and i-Pr2NEt to give β-keto thioesters. Prior enolate formation is not required and the reaction is conducted using untreated dichloromethane open to the air.

  在MgBr2·OEt2和i-Pr2NEt处理下，硫酯通过化学选择性软烯醇化和N-酰基苯并三氮唑酰化，生成β-酮硫酯。无需先形成烯醇盐，反应在未经处理的二氯甲烷中进行，且对空气开放。

• Direct Carbon−Carbon Bond Formation via Chemoselective Soft Enolization of Thioesters: A Remarkably Simple and Versatile Crossed-Claisen Reaction Applied to the Synthesis of LY294002
  作者：Guoqiang Zhou、Daniel Lim、Don M. Coltart

  DOI：10.1021/ol801498u

  日期：2008.9.1

  Thioesters undergo chemoselective soft enolization and acylation by N-acylbenzotriazoles on treatment with MgBr(2)center dot OEt(2) and i-Pr(2)NEt to give beta-keto thioesters. Prior enolate formation is not required, and the reaction is conducted using untreated CH(2)Cl(2) open to the air. The coupled products are stable synthetic equivalents of beta-keto acids and can be converted directly into beta-keto esters, beta-keto amides, and beta-diketones under mild conditions. The utility of this carbon-carbon bond-forming method is shown through the synthesis of the PI3-K inhibitor LY294002.
