Enzymatic Synthesis of Enantiopure Precursors of Chiral Bidentate and Tridentate Phosphorus Catalysts
Abstract The Candida antarctica lipase (CAL‐B)‐catalyzed acetylation of racemic 2‐hydroxymethylphenyl(methyl)phenylphosphine oxide, performed in diethyl ether, led to kinetic resolution with an unusually high enantioselectivity ( E =3000). The CAL‐B‐mediated desymmetrization of prochiral bis(2‐hydro...
