标题:Chiral synthesis of alpha-aminophosponic acids
发明人：CAMPBELL DAVID A
权利人:AFFYMAX TECH NV
摘要:A stereospecific method of preparing alpha-aminophosphonic acids and derivatives thereof is provided. A protected amino acid is converted to a acyl aroyl or diacyl peroxide which spontaneously rearranges to form an alpha-amino ester. This rearrangement occurs stereospecifically with retention of configuration. The ester is subsequently converted to an appropriate leaving group and displaced with a phosphite yielding a chiral alpha-aminophosphonic acid or derivative. n Alpha-aminophosphonic acids are useful for the synthesis of peptide analogs that possess a phosphonate linkage in the place of an amide linkage. This substitution can impart protease resistance in therapeutic peptides thereby increasing the serum half-life.
