  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.
