(+)-6-Methyloctanoic (isopelargonic) acid, the fatty acid component of certain polypeptide antibiotics known as polymyxins, has been synthesized by a new route, starting from (−)-2-methylbutanol-(1). The protected dipeptide Nα-(+)-Isopelargonyl-Nγ-benzyloxycarbonyl-D-α,γ-diaminobutyryl-L-threonine, corresponding to the side chain of two structures which have been proposed for polymyxin B1, was obtained
(+)-6-甲基辛酸(异壬酸)是某些多肽抗生素(称为多粘菌素)的脂肪酸成分,是通过一种新的途径合成的,从(-)-2-甲基丁醇-(1)开始。的保护的二肽ñ α - (+) - Isopelargonyl-N γ苄氧基羰基d-α,γ二氨基-L-苏氨酸,对应于已经提出了用于多粘菌素B两种结构的侧链1,这是由获得已知的肽偶联方法。
