  Alkylation of H-Phosphinate Esters under Basic Conditions

  摘要：

  An efficient and general procedure was developed for the direct alkylation of H-phosphinate esters with LHMDS at low temperature. The simplicity of the reaction allows the use of various H-phosphinate esters and takes place with a wide range of electrophiles. The approach can be employed to access some GABA analogues or precursors to GABA analogues. The isolated yields are moderate to good. This is the first report of an alkylation with a secondary iodide or a primary chloride.

  phosphinate, which then led to the development of a Pd-catalyzed rearrangement of preformed allylic phosphinates esters and, ultimately, to a catalytic dehydrative allylation of hypophosphorous acid with allylic alcohols. The reactions disclosed herein constitute efficient synthetic approaches, not only to prepare allylic H-phosphinic acids but also their esters via one-pot tandem processes. In addition

  This account summarizes the research conducted in our laboratory over the past five years. New methodologies were devised for the formation of P–C bonds with a focus on the reactions of hypophosphorous acid derivatives. Three types of reactions have been developed: palladium-catalyzed cross-coupling, room-temperature radical addition, and palladium-catalyzed addition. Our results are summarized in

  该报告总结了过去五年来我们实验室进行的研究。设计了新的方法来形成P-C键，重点是次磷酸衍生物的反应。已经开发出三种类型的反应：钯催化的交叉偶联，室温自由基加成和钯催化的加成。我们在所有这些领域中总结了我们的结果，其中包括一些我们的最新数据。（1）我们的钯催化交叉偶联已扩展到烷基次膦酸酯与各种芳基，杂芳基甚至烯基亲电试剂的直接偶联。（2）在自由基条件下添加次磷酸钠从烯烃延伸至炔烃。

  A novel palladium-catalyzed allylation of H3PO2 with allylic alcohols is described. The phosphorus-carbon bond-forming reaction produces allylic-H-phosphinic acids and water, in the absence of additives. Primary H-phosphinic acids are obtained in excellent yields, whereas secondary H-phosphinic acids react sluggishly. A reusable polymer-supported catalyst is also described. The reaction provides an

  Simple alkyl phosphinates prepared by the silicate esterification method can be alkylated under Barbier-like conditions with butyl lithium at -78 °C followed by warming to room temperature. The method is limited to the more reactive electrophile such as allylic bromides and alkyl iodides. With these electrophiles good yields of H-phosphinic acid esters are generally obtained in a straightforward manner

  通过硅酸酯化方法制备的简单烷基次膦酸盐可以在类似巴比尔的条件下与丁基锂在 -78 °C 下烷基化，然后升温至室温。该方法仅限于反应性更强的亲电子试剂，例如烯丙基溴化物和烷基碘化物。使用这些亲电子试剂，通常以简单的方式获得高产率的 H-次膦酸酯。
