The easily available cycloalkanoyl acetic- and propionic acid esters are transformed to the corresponding amines by standard procedures. These in turn provided an efficient access to cyclic α-aminonitriles, which were reacted with a series of Grignard reagents yielding stereoselectively the cis -configured title compounds; the scope and limitation of this route were investigated. The stereochemical
通过标准方法将容易获得的环烷酰基乙酸和丙酸酯转化为相应的胺。这些反过来又提供了有效的环状α-氨基腈的途径,使之与一系列 格氏 试剂反应,产生立体选择性的 顺式 构型标题化合物。研究了这条路线的范围和局限性。通过X射线晶体学和NMR光谱法实现立体化学分配。
