摘要

α-氨基酮是药物和合成化学中必不可少的结构基序。在这项研究中，我们描述了一种新的合成方法，该方法涉及级联加成反应，随后是刘易斯酸催化的亚甲基亚氮吡啶和羧酸的重排。此外，我们开发了一种高速连续流合成方法，使反应在3.5分钟内有效地进行。在这个连续流系统中加入了一个更环保的硅胶填充催化柱，有效地促进了重排步骤，为合成α-酰胺酮化合物提供了更环保的方法。

A Cascade Markovnikov Addition / Lewis Acid-Catalyzed Rearrangement of Methyleneaziridines and Carboxylic Acids: Continuous-Flow Synthesis of α-Amidoketones

α-Amidoketones are essential structural motifs in pharmaceuticals and synthetic chemistry. In this study, we describe a novel synthetic method that involves a cascade addition reaction, followed by a Lewis acid-catalyzed rearrangement of methyleneaziridines and carboxylic acids. Additionally, we developed a high-speed continuous flow synthesis method, allowing the reaction to proceed efficiently within 3.5 minutes. The incorporation of a greener silica gel-packed catalyzed column in this continuous flow system effectively facilitates the rearrangement step, providing a more environmentally friendly approach for synthesizing α-amidoketone compounds.
