The stereoselective synthesis of a series of di- and tri-hydroxylated aminocyclohexane derivatives has been developed. A one-pot, two step tandem process involving an Overman rearrangement and a ring closing metathesis reaction has been utilised for the asymmetric synthesis of (1S)-1-(2′,2′,2′-trichloromethylcarbonylamino)cyclohexa-2-ene. Oxidation of this cyclohexene derivative was then studied leading
已经开发了一系列二和三羟基化的氨基环己烷衍生物的立体选择性合成。一锅,两步串联过程涉及超人重排和闭环易位反应已用于不对称合成(1 S)-1-(2',2',2'-三氯甲基羰基氨基)环六-2-烯。然后研究了这种环己烯衍生物的氧化反应,从而制备了具有出色立体选择性的两种二醇类似物。然后将(1 S)-1-(2',2',2'-三氯甲基羰基氨基)环己-2-烯通过4,5-二氢-1,3-恶唑 通过Upjohn二羟基化条件或通过反应的直接环氧化/水解顺序对该烯丙基醇进行官能化,可以以优异的立体选择性合成两种二氢conduramines。通过NOE实验或X射线结构确定,确认了所制备的所有化合物的立体化学归属。
