Highly Efficient Asymmetric Michael Addition of Diaryl Phosphine Oxides to α,β‐Unsaturated N‐Acylated Oxazolidin‐2‐ones

Abstract

A highly efficient asymmetric Michael reaction of diaryl phosphine oxides 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. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
