We report the use of benzylamine as the amine component in Hantzsch ester mediated and chiral Bronsted acid catalyzed enantioselective reductive aminations of ketones. The method is noteworthy because the benzyl group is easily removable, and amine product purification is achieved through Hantzsch ester oxidation product removal via basic hydrolysis.
我们报告了在 Hantzsch 酯介导和手性布朗斯台德酸催化的酮的对映选择性还原胺化中使用
苄胺作为胺组分。该方法值得注意,因为苄基很容易去除,胺产物纯化是通过碱性
水解去除Hantzsch酯氧化产物来实现的。
