 Extensive work has been reported on asymmetric hydroxylation of prochiral enolates with camphorsulfonyloxaziridine derivatives , achieving moderate to high enantiomeric excess . The commonly accepted proposed transition state that justifies this stereochemical outcome involves an open transition state where the steric bulk of R1 determines the face of approach .
