A highlyefficientasymmetricMichael reaction of diarylphosphineoxides with α,β‐unsaturated N‐acylated oxazolidinones has been developed. Excellent enantioselectivities (up to >99 % ee) and chemical yields (up to 99 %) were achieved with a broad substrate scope of the oxazolidinones. The bidentate property of oxazolidinones was found to be critical for high enantioselectivities.
