Recently, dual‐catalytic strategies towards the decarboxylative elimination of carboxylic acids have gained attention. Our lab previously reported a photoredox/cobaloxime dual catalytic method that allows the synthesis of enamides and enecarbamates directly from N‐acyl amino acids and avoids the use of any stoichiometric reagents. Further development, detailed herein, has improved upon this transformation's
近来,用于羧酸脱羧消除的双重催化策略已引起关注。我们的实验室以前曾报道过光氧化还原/钴肟双催化方法,该方法可直接从N酰基氨基酸合成酰胺和烯甲酸酯,并避免使用任何化学计量试剂。本文详述的进一步开发改进了这种转化的用途,进一步的实验为反应机理提供了新的见解。这些新的发展和见识有望帮助扩大光氧化还原/钴双催化系统。
