摘要
Asymmetric desymmetrization of sigma-symmetric acid anhydrides was achieved with chiral phosphoric acid as a Bronsted acid catalyst. The key of success was finding of benzhydrol and 2,2-diphenylethanol as the nucleophiles of choice. The corresponding half esters were obtained in good yields with high selectivity.
