Catalytic asymmetric alkylation of achiral lithium enolates of 1-tetralone and cyclohexanone with reactive alkyl halides was realized by using a combination of a chiral tetradentate amine (∼0.05 equiv.) and an achiral bidentate amine (2 equiv.).
通过使用手性四齿胺(〜0.05当量)和非手性二齿胺(2当量)的组合,实现了1-四氢萘酮和环己酮的非手性烯醇锂与反应性烷基卤的催化不对称烷基化。
