A simple one-pot procedure enables the sequential, regioselective, and diastereoselective introduction of the same or two different substituents to the α- and α′-positions of unprotected azacycles. Aryl, alkyl, and alkenyl substituents are introduced via their corresponding organolithium compounds. The scope of this transformation includes pyrrolidines, piperidines, azepanes, and piperazines.
简单的一锅法能够连续、区域选择性和非对映选择性地将相同或两个不同的取代基引入到未受保护的氮杂环的α-和α'-位置。芳基、烷基和烯基取代基通过其相应的有机锂化合物引入。该转化的范围包括吡咯烷、哌啶、氮杂环庚烷和哌嗪。
