Solid phase reduction of oxazolones using BER-Ni₂B-A simple synthesis of N-benzoylphenylaJanines

2878-2881Borohydride 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-benzoylphenyl alanines and hence the corresponding amino acids
