D. Lucet et al., Enantioselective synthesis of alpha-amino acids and monosubstituted 1,2-diamines by conjugate addition of 4-phenyl-2-oxazolidinone to nitroalkenes, EUR J ORG C, (10), 1999, pp. 2583-2591
The addition of the potassium salt of (R)- or (S)-4-phenyl-2-oxazolidinone
to monosubstituted nitroalkenes proceeded with very good diastereoselectivi
ty. Several of the addition products were converted into a-amino acids and
monosubstituted 1,2-diamines of high enantiomeric purity.
