摘要：
Herein, we report a novel synthesis of 1,3-oxazin-6-ones from enamides with CO2 through CH carboxylation and one-pot cyclization. This transition-metal-free and redox-neutral process features broad substrate scope, good functional group tolerance and facile product derivatization. The nucleophilic attack to CO2 from the electron-rich alkene is demonstrated for this reaction.
