effective and practical modular flow design for the meta-selective C-H arylation of anilines. The design consists of four continuous-flow modules (i.e., diaryliodonium salt synthesis, meta-selective C-H arylation, inline copper extraction, and aniline deprotection) which can be operated either individually or consecutively to provide direct access to meta-arylated anilines. With a total residence time
本文描述的是用于苯胺间位选择性CH芳基化的有效且实用的模块化流程设计。该设计由四个连续流模块(即二芳基碘鎓盐合成、间位选择性CH芳基化、在线铜萃取和苯胺脱保护)组成,这些模块可以单独或连续操作以提供间位芳基化苯胺的直接获取。总停留时间为1小时,无需柱层析即可高收率、高纯度地获得所需产物,且残留铜含量满足非肠道给药原料药的标准。
