We report the photo-mediated 1,2-aryl migration of 2‑chloro-1-arylpropanones to 2-arylpropionic acids using HCOONa as an acid scavenger. This pragmatically focused study obviates the multiple-step sequence in the industrially employed, ZnO-promoted rearrangement strategy, and offers rapid access to various 2-arylpropionic acids under environmentally friendly conditions. Furthermore, the successful
我们报道了使用 HCOONa 作为酸清除剂,光介导的 2-氯-1-芳基丙酮向 2-芳基丙酸的 1,2-芳基迁移。这项务实的研究避免了工业上采用的 ZnO 促进的重排策略中的多步骤顺序,并提供了在环境友好的条件下快速获得各种 2-芳基丙酸的方法。此外,该批量光化学成功转移到连续流动平台,提高了可扩展性,并实现了洛索洛芬的克级合成。
