  A New and Efficient Synthesis of α-Amino Cycloalkyl-Phosphonic AcidsviaElectrophilic Azidation of Cycloalkylphosphonates

  摘要：

  alpha-Amino cyclobutyl-, cyclopentyl- and cyclohexylphosphonic acids (13) were efficiently prepared from the related unsubstituted cycloalkphosphonates (5), in three steps including electrophilic azidation of the corresponding lithiated carbanions, hydrogenation of the intermediate alpha-azido cycloalkyl-phosphonates (10) and acidic hydrolysis of the resulting alpha-amino cycloalkyl-phosphonates (12).

• Copper‐Catalyzed C−P Cross‐Coupling of (Cyclo)alkenyl/Aryl Bromides and Secondary Phosphine Oxides with <i>in</i>   <i>situ</i> Halogen Exchange

  A protocol for copper-catalyzed halogen exchange/C−P cross-coupling between (cyclo)alkenyl/aryl bromides and secondary phosphine oxides has been developed. The addition of sodium iodide increases the yield of the cross-coupling by promoting in situ halogen exchange of organic bromides to the corresponding iodides.
