Organotitanium complexes 3–5 prepared from a Ti(O-i-Pr)4/2/i-PrMgX reagent (2) and the corresponding unsaturated compounds reacted with Garner's aldehyde (1) to provide anti-addition products highly predominantly, thus allowing an easy access to a variety of optically active anti-1,2-aminoalcohol derivatives.
有机钛络合物3 - 5从由Ti制备(O-我-Pr)4 /2 /我-PrMgX试剂(2)和相应的不饱和化合物与加纳的醛(反应1),以提供抗高度主要-addition产品,从而允许容易获得各种光学活性的抗-1,2-氨基醇衍生物。
