摘要

2-烷基吡啶的直接对映选择性共轭加成可以高效地构建具有连续立体中心的复杂功能化吡啶基支架。该方法利用手性锂酰胺作为无迹立体定向助剂，通过有机锂中间体的特定聚集来实现出色的对映和非对映控制。

Chiral Lithium Amides as Key Reagents in Enantioselective Synthesis of 2-Alkylpyridines with Multiple Stereocenters.

A direct enantioselective conjugate addition of 2-alkylpyridines enables efficient construction of complex functionalized pyridinyl scaffolds with contiguous stereocenters. This method leverages chiral lithium amides as traceless stereodirecting auxiliaries, operating through defined aggregation of organolithium intermediates to achieve excellent enantio- and diastereocontrol.
