  Direct Carbon−Carbon Bond Formation via Soft Enolization:  A Facile and Efficient Synthesis of 1,3-Diketones

  摘要：

  Ketones undergo soft enolate formation and acylation on treatment with MgBr2 center dot OE2, i-Pr2NEt, and various acylating agents to give 1,3-diketones. The process is particularly efficient for N-acylbenzotriazoles and O-Pfp esters, and, in these cases, is conducted with untreated, reagent-grade CH2Cl2 open to the air, thus providing an exceptionally simple approach to the synthesis of this important class of compounds.

  Ketones undergo soft enolization and acylation on treatment with MgBr2·OEt2, i-Pr2NEt, and various acylating agents to give 1,3-diketones. The process is particularly efficient for N-acylbenzotriazoles and O-pentafluorophenyl esters, and, in these cases, is conducted using untreated, reagent grade CH2Cl2 open to the air, thus providing an exceptionally simple approach to the synthesis of this important class of compounds.

  酮在与MgBr2·OEt2、i-Pr2NEt和各种酸酐处理时发生温和的烯醇化和酰化反应，生成1,3-二酮。该过程对N-酰基苯并三唑和O-五氟苯基酯特别高效，并且在这些情况下，使用未处理的试剂级CH2Cl2在开放空气中进行，从而提供了一种极其简单的方法来合成这一重要化合物类。
