摘要

Two short syntheses of DN-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.
