  Asymmetric synthesis of 3,5-bis(isopropyloxy)-4-methoxyphenyl glycine by way of a diastereoselective Strecker reaction and an Evans electrophilic amination reaction

  摘要：

  Two short syntheses of D-N-Boc-3,5-bis(isopropyloxy)-4-methoxyphenyl glycine, a central unit of vancomycin type antibiotics, have been developed. A diastereoselective Strecker reaction using (S)-phenylglycinol as a chiral inducer was the key step in the first synthesis, while Evans' electrophilic amination technology was employed for introducing both the amino function and the chirality in the second strategy.

• 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

  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.
