The reactions of organolithiums with the new chiral hydrazones derived from (S)-indoline-2-carboxylic acid afforded chiral hydrazines with high diastereoselectivities (up to 99% de) and the present method was utilized for the preparation of high optically pure (R)-coniine (94% ee).
有机锂与衍生自(S)-二氢吲哚-2-羧酸的新手性的反应提供了具有高非对映选择性(高达99%de)的手性肼,本方法用于制备高旋光纯(R) -coniine(94%ee)。
