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.
Silver-catalyzed three-component reaction of propargylic amines, carbon dioxide, and N-iodosuccinimide for stereoselective preparation of (E)-iodovinyloxazolidinones

The silver-catalyzed three-component reaction of propargylic amines, carbon dioxide, and N-iodosuccinimide for the stereoselective synthesis of (E)-iodovinyloxazolidinones was developed. The silver-catalytic system could be applied to various propargylic amines to afford the corresponding iodovinyloxazolidinones in high yields. The structure of the oxazolidinone was confirmed by X-ray structure analysis to be the Eisomer for the geometry of the exo-olefin. The silver-catalyzed cyclization and replacement of silver with the iodine group in the intermediate were thought to be crucial steps.
