Towards total synthesis of a series of kinamycin and related antibiotics via common synthetic intermediates, total synthesis of prekinamycin was achieved via Suzuki coupling of naphthaleneboronic acid and bromobenzene derivative, intramolecular FriedelCrafts reaction of 2‐(naphthalen‐2‐yl)benzoic acid, and diazotization in ten steps from 3,5‐dimethylphenol. Synthetic studies towards kinamycin antibiotics
向一系列kinamycin和相关抗生素的总合成经由共同合成中间体,prekinamycin的总合成达到通过铃木萘硼酸和溴苯衍生物的偶联,分子内弗里德尔工艺品的2-(萘-2-基)苯甲酸反应,然后从3,5-二甲基苯酚分十步进行重氮化。还审查了对卡那霉素抗生素的合成研究,并合成了卡那霉素的四环醌核心。具有AB-D环部分的苯甲酸衍生物的钯催化的位点选择性羟基化已成功地应用于选择性D环官能化。
