摘要

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 corresponding cyclic urethane as a single trans-diastereomer.
