Following the thio-conjugate addition of (±)-9, its enantiomers were extremely efficiently discriminated using Novozym 435®. The thio-differentiating unit may then be removed either under reductive conditions, using Raney nickel, or following an ox

Polyamino acids, such as polyleucine, behave as synthetic enzymes in the asymmetric epoxidation of chalcone and other electron-deficient alkenes (the Julia–Colonna reaction). The influences of reaction conditions, of the molecular structure of the
