convenient method for the solid-phase synthesis of putative linear heptapeptide intermediates in vancomycin biosynthesis is described, in particular, the heptapeptide D-Leu-Cyt-L-Asn-Hpg-Hpg-Cyt′-Dhpg (Cyt=(2R,3R)-m-chloro-3-hydroxytyrosine, Hpg=(R)-2-(p-hydroxyphenyl)glycine, Cyt′=(2S,3R)-m-chloro-3-hydroxytyrosine and Dhpg=(S)-2-(3,5-dihydroxyphenyl)glycine). The synthesis was performed on chlorotrityl resin
描述了一种在万古霉素生物合成中固相合成假定的线性七肽中间体的简便方法,特别是七肽 D-Leu-Cyt-L-Asn-Hpg-Hpg-Cyt'-Dhpg (Cyt=(2R,3R )-m-chloro-3-hydroxytyrosine, Hpg=(R)-2-(p-hydroxyphenyl)glycine, Cyt'=(2S,3R)-m-chloro-3-hydroxytyrosine and Dhpg=(S)-2- (3,5-二羟基苯基)甘氨酸)。该合成是在氯三苯甲基树脂上进行的,并在肽链组装过程中使用(烯丙氧基)羰基保护基团进行临时 N(α)保护。
