Synthesis of Phosphoryl Amino Acids Chrysin Esters

Abstract

The N-phosphoryl amino acids are coupled with chrysin to form phosphoryl amino acids chrysin esters. Five of its new analogs have been synthesized. The structures of all the newly synthesized chrysin derivatives were confirmed by ESI-MS, NMR and IR.

Keywords:

• 5, 7-dihydroxyflavone
• N-phosphoamino acids
• phosphoryl amino acids chrysin esters
