ChemInform Abstract: STUDIES ON HYDROXY AMINO ACIDS. VI. FORMATION OF THE OXAZOLINE DERIVATIVES FROM N-ACYL-β-HYDROXY AMINO ACID PEPTIDES

Oxazoline derivatives were mainly obtained from the O-tosyl-N-acyl-β-hydroxy amino acid peptides by β-elimination reaction. Dehydroalanine or hydantoin derivatives were isolated when the urethane type acyl groups were used.
