Construction of the Oxazolidinone Framework from Propargylamine and CO2 in Air at Ambient Temperature: Catalytic Effect of a Gold Complex Featuring an L2/Z‐Type Ligand

The metal‐catalyzed carboxylation of propargylamines with aerial CO2 at room temperature to form 5‐methyleneoxazolidin‐2‐one derivatives has been developed. In this reaction, the catalyst [Au(dpbF)]X featuring a Z‐type ligand gave the best results, presumably due to the σ‐acceptance of the borane atom. The carboxylation of propargylamines with aerial CO2 at room temperature to form 5‐methyleneoxazolidin‐2‐one derivatives has been developed by using a gold catalyst featuring a Z‐type ligand.
