A general, mild, and chemoselective one-pot oxidation/imine-iminium formation/nucleophilic addition sequence allowing the N-alkylation of amines by alcohols is described. This metal-free, one-pot sequence produced a wide variety of amines in good yields and diastereoselectivities, without the epimerization of the enantioenriched amines or alcohols involved in the process. This method was applied to
描述了一种通用的、温和的、化学选择性的一锅氧化/亚胺-亚胺盐形成/亲核加成序列,允许通过醇对胺进行 N-烷基化。这种不含金属的一锅法以良好的收率和非对映选择性生产了多种胺,而该过程中没有对映体富集的胺或醇的差向异构化。该方法被应用于生物活性化合物西那卡塞和右氧雄酮的合成。
