A highly enantioselective intramolecular N‐heterocyclic carbene (NHC)‐catalyzed hydroacylation reaction gives access to a range of cyclic ketones from unactivated olefin‐substituted aldehydes (up to 99 % ee). Remarkably, aliphatic aldehydes were also transformed efficiently in an NHC‐catalyzed hydroacylation reaction for the first time.
高度对映选择性的分子内N杂环卡宾(NHC)催化的加氢酰化反应可从未活化的烯烃取代的醛(至多99%ee)中获得一系列环酮。值得注意的是,脂肪醛也首次在NHC催化的加氢酰化反应中得到了有效转化。
