A chiral disulfonimide (DSI)‐catalyzedasymmetric reduction of N‐alkyl imines with Hantzsch esters as a hydrogen source in the presence of Boc2O has been developed. The reaction delivers Boc‐protectedN‐alkyl amines with excellent yields and enantioselectivity. The method tolerates a large variety of alkyl amines, thus illustrating potential for a general reductive cross‐coupling of ketones with diverse

The use of [Cp*IrI2]2 as an efficient catalyst for the alkylation of amines by alcohols in either water or ionic liquid is described. Primary amines are converted into secondaryamines, and secondaryamines into tertiaryamines in the absence of base, and the chemistry has been applied to the synthesis of the analgesic fentanyl. The conversion of primary amines into N-heterocycles by the reaction with
描述了使用[Cp * IrI 2 ] 2作为在水或离子液体中通过醇使胺烷基化的有效催化剂。在不存在碱的情况下,伯胺被转化为仲胺,仲胺被转化为叔胺,并且该化学方法已经应用于止痛药芬太尼的合成。还描述了通过与二醇反应将伯胺转化为N-杂环以及磺酰胺的N-烷基化。

conversion of lignin into heteroatom functionalized chemicals is of great importance to bring the biorefinery concept into reality. Herein, a new strategy was designed for direct transformation of lignin β-O-4 model compounds into benzylamines and phenols in moderate to excellent yields in the presence of organic amines. The transformation involves dehydrogenation of Cα−OH, hydrogenolysis of the Cβ−O
