Enantiomerically pure phosphines are extremely important ligands for a wide range of catalytic enantioselective reactions, including stereoselective hydrogenations. However, their synthesis is often challenging and requiring ready access to suitable phosphorus-containing chiral intermediates, such as phosphine–boranes. The group of Professors Antoni Riera and Xavier Verdaguer from the Institute of Research in Biomedicine (IRB Barcelona) and the University of Barcelona (Spain) have reported a convenient entry to phosphine–boranes in both enantiomerically pure forms.
Professors Antoni Riera and Xavier Verdaguer said: “This is an important P-stereogenic building block for phosphine ligand synthesis, and we hope that the novel methodology makes this compound readily available to the chemistry community.”
