Asymmetric synthesis of (2S,3R) β-(4-F-3-NO2) phenyl serine, D-(R)-4-methoxy-3,5-bistbutyldimethylsiloxy phenylglycine and their assemblage to C-O-D ring of vancomycin
摘要:
The asymmetric synthesis of two appropriately functionalized non-proteinogenic amino acids 2 and 3 needed for the total synthesis of vancomycin was described. The assemblage of these amino acids into linear tripeptide followed by biaryl ether formation via intramolecular SNAr reaction led to the fully functionalized C-O-D ring of vancomycin.
