Borohydride exchange resin (BER)-Ni2B is successfully used as a reagent for the solid phase reduction of the C-4 exocyclic double bond of oxazolones to give the N-benzoylphenylalanines and hence the corresponding amino acids.
SYNTHESIS OF FLUORINATED α-AMINO KETONES PART I: α-BENZAMIDOALKYL MONO- DI- AND TRIFLUOROMETHYL KETONES

2-Phenyl-5(4H)-oxazolones, obtained from α-amino acids, are reacted with di- and trifluoro acetic anhydride by a modified Dakin-West procedure to yield in a one-pot reaction α-benzamidoalkyl-di- and trifluoromethyl ketones in good yields.The monofluoromethyl analogues were also prepared from α-amino acids, however the use of the highly toxic fluoroacetic anhydride was avoided.The key step is the halogen exchange reaction on the corresponding bromomethyl ketone.
