Urethane synthesis via oxidative decarboxylation of oxamic acids under mild electrochemical conditions is reported. This simple phosgene-free route to urethanes involves an in situ generation of isocyanates by anodic oxidation of oxamic acids in an alcoholic medium. The reaction is applicable to a wide range of oxamic acids, including chiral ones, and alcohols furnishing the desired urethanes in a
报道了在温和的电化学条件下通过草酸的氧化脱羧合成氨基甲酸酯。这种简单的无光气的氨基甲酸酯途径涉及在酒精介质中通过草酸的阳极氧化原位生成异氰酸酯。该反应适用于广泛的草酰胺酸,包括手性酸,以及在不使用化学氧化剂的情况下,通过一锅法即可提供所需氨基甲酸酯的醇。
