Palladium-catalyzed carboxylative cyclization of a-allenyl amines in dense carbon dioxide

Carboxylative transformation of 2,3-allenic amines into 5-vinyl-1,3-oxazolidin-2-ones was promoted by palladium catalysts under a pressurized CO2 condition. The presence of a stereogenic center adjacent to the allene group resulted in the formation of the
