A very simple and efficient stereoselective approach to cis-2,3-disubstituted piperidines via the reduction of N-acyliminium ion intermediates is described. Application of this methodology is exemplified by the enantioselective total synthesis of (+)-(2S,3S)-CP-99,994.
描述了一种非常简单有效的立体选择方法,该方法通过还原N-酰基亚胺离子中间体来制备顺式-2,3-二取代的哌啶。该方法的应用以(+)-(2 S,3 S)-CP-99,994的对映选择性全合成为例。
