The concept of chiral docking/protectinggroups for biohydroxylation was extended from cyclopentanone to other ketones. Reaction of cyclohexanone, (R)-3-methylcyclohexanone, cycloheptanone, 5-methyl-2-hexanone and 4-methyl-2-pentanone with (R)-2-amino-1-propanol and subsequent in situ benzoylation afforded the corresponding N-benzoylated oxazolidine derivatives. All substrates were hydroxylated with
