The first catalytic enantioselective synthesis of ambiphilic phosphine boronate esters is presented. The asymmetric boration of α,β‐unsaturated phosphine oxides catalyzed by a copper bisphosphine complex affords optically active organoboronate esters that bear a vicinal phosphine oxide group in good yields and high enantiomeric excess. The synthetic utility of the products is demonstrated through...
Die Kupplung zweier Schlüsselelemente liefert eine Route zu chiralen ambiphilen Phosphinboronaten, die als frustrierte Lewis‐Paare agieren können und eine Reihe von Transformationen ermöglichen, die sich mit den einzelnen Komponenten nur schwer erzielen lassen. B. L. Feringa, V. Hornillos et al. präsentieren in ihrer Zuschrift auf S. 7978 ff. die erste katalytische enantioselektive Synthese dieser...
