H. Collet et al., A NEW SIMPLE AND QUANTITATIVE SYNTHESIS OF ALPHA-AMINO-ACID-N-CARBOXYANHYDRIDES (OXAZOLIDINES-2,5-DIONE), Tetrahedron letters, 37(50), 1996, pp. 9043-9046
Nitrosation of chiral N-cartarnoylaminoacids with a mixture of NO and
O-2 gives, with the same con figuration and in quantitative yield the
corresponding alpha-aminoacid-N-carboxyanhydrides (NCA), well known pr
ecursors of peptides. The by products of this reaction are N-2 and H2O
