A facile, convenient, and one‐pot multi‐step synthesis of substituted piperidin‐2‐ones from the Baylis–Hillman alcohols derived from various aldehydes and acrylonitrile, involving Johnson–Claisen rearrangement, reduction of an α,β‐unsaturated nitrile moiety into the saturated amine‐skeleton, followed by cyclization, in an operationally simple procedure, is described.
从多种醛和丙烯腈衍生的Baylis - Hillman醇轻松,方便且一步一步地合成取代的哌啶-2-酮,涉及Johnson - Claisen重排,将α,β-不饱和腈部分还原为描述了在操作简单的过程中饱和胺骨架并随后环化的过程。
