REGIOSELECTIVE TRANSFORMATION OF UNSYMMETRICAL BIS(N-NITROSOSULFONAMIDES) LEADING TO OPTICALLY ACTIVE CYCLIC IMINO ACID DERIVATIVES FROM L-LYSINE AND L-ORNITHINE

Article abstract of DOI:10.1246/cl.1985.1941

Chiral cyclic imino acid derivatives were prepared from unsymmetrical bis(N-nitrososulfonamides) of diaminocarboxylic acids, L-lysine and L-ornithine, in good yields through kinetically controlled regioselective N-nitrososulfonamide-sulfonate rearrangement.
