The first organocatalytic enantioselective CH alkenylation and arylation reactions of N‐carbamoyl tetrahydropyridines and tetrahydro‐β‐carbolines (THCs) are described. The metal‐free processes represent an efficient and straightforward approach to a variety of structurally and electronically diverse α‐substituted tetrahydropyridines and THCs in good yields with excellent regio‐ and enantioselectivities
描述了N-氨基甲酰基四氢吡啶和四氢-β-咔啉(THC)的第一个有机催化对映选择性CH烯基化和芳基化反应。无金属工艺代表了一种高效,直接的方法,可以以良好的产率,优异的区域选择性和对映体选择性,对各种结构和电子形式多样的α-取代的四氢吡啶和四氢呋喃进行处理。初步的控制实验提供了对反应机理的重要见解。
