  Anodic oxidation of chiral sulfinylamines: a new route to highly diastereoselective α-alkylation of piperidine

  摘要：

  The anodic oxidation of some chiral non-racemic N-arylsulfinyl piperidines was investigated and for the first time alpha methoxylated sulfinyl piperidines were obtained. The so-formed compounds are equivalent of chiral N-sulfinyliminiums and used as new intermediates for the preparation of chiral alpha-substituted piperidine derivatives in good yield and diastereoselectivity.

• N-Sulfinyl Amines as a Nitrogen Source in the Asymmetric Intramolecular Aza-Michael Reaction: Total Synthesis of (−)-Pinidinol

  N‐Sulfinyl amines have been successfully employed as nitrogen nucleophiles for the asymmetric intramolecular aza‐Michael reaction. The synthetic strategy involves a cross‐metathesis reaction followed by the Michael‐type cyclization, either in a base‐catalyzed two‐step procedure or in a tandem fashion. The developed methodology allows access to chiral substituted pyrrolidines and piperidines bearing

  N-亚磺胺已被成功地用作不对称分子内氮杂-Michael反应的氮亲核试剂。合成策略涉及交叉易位反应，然后进行迈克尔型环化反应，可采用碱催化的两步法或串联方式进行。发达的方法学允许访问带有一个或两个立体中心的手性取代的吡咯烷和哌啶，并且该方法已用于哌啶生物碱（-）-哌啶子醇的合成。
