tool, the “Non-Oxidative” Chloro-Pummerer Reaction (NOCPR), which allows for the use of enantiomerically pure α-Li alkylsulfoxides as chiral α-chloroalkyl carbanions with N-protected imines. In this reaction the sulfinyl group of N-alkoxycarbonyl-β-sulfinylamines derived from aryl-, fluoroalkyl- and alkylimines is displaced by a chlorine atom in a one-pot reaction with clean stereoinversion at carbon.
本文介绍了一种新的、有用的合成工具,即“非氧化性”氯-Pummerer 反应 (NOCPR),它允许使用对映异构纯的 α-Li 烷基亚砜作为手性 α-氯代烷基碳负离子与 N 保护的亚胺。在该反应中,衍生自芳基-、氟烷基-和烷基亚胺的 N-烷氧基羰基-β-亚磺酰基胺的亚磺酰基在一锅反应中被氯原子取代,并在碳上进行了彻底的立体转化。通过 NOCPR 产生的几种 1,2-氯胺转化为相应的氮丙啶。(© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
