The synthesis of novel chiral nitrogen ligands and their precursors is described. They consist of an optically active oxazoline bound to pyridine in the 2-position. In addition, another optically active substituent is attached to the pyridine ring. The effect of the two independent stereogenic units in one ligand was studied in the Rh(I)-catalysed enantioselective hydrosilylation of acetophenone with
描述了新型手性氮配体及其前体的合成。它们由在2位上结合吡啶的旋光性恶唑啉组成。另外,另一个光学活性取代基连接到吡啶环上。在Rh(I)催化的苯乙酮与二苯基硅烷的对映选择性氢化硅烷化反应中,研究了一个配体中两个独立的立体生成单元的作用。
