A simple, scalable, and sustainable access to salicylamides from O-aryl carbamates was achieved using lithium amides as easy-to-handle metalating agents under bench-type aerobic conditions. Tunable regioselective ortho- and lateral metalations in eco-friendly cyclopentyl methyl ether (CPME) allow fast anionic migrations under air, with an unexpected beneficial contribution from biorenewable protic
在台式需氧条件下,使用氨基锂作为易于处理的金属化剂,可以从O-芳基氨基甲酸酯中简单、可扩展且可持续地获取水杨酰胺。生态友好型环戊基甲基醚 (CPME) 中的可调区域选择性邻位和侧位金属化允许阴离子在空气中快速迁移,并具有来自生物可再生质子共晶混合物的意想不到的有益贡献。
