摘要：

The first asymmetric (C-P)-connective synthesis of alpha-phosphinoketones in high enantiomeric purity (e.e. 91-97 %) is described. Key step is the highly diastereoselective phosphinylation of SAMP-hydrazones (S)-2 to produce alpha-phosphinohydrazones (S,R)-3, isolated as the more stable borane adducts. Subsequent ozonolysis afforded the title compounds (R)-4, potential ligands for enantioselective homogeneous catalysis.
