The first synthesis of 7-prenylisatin, an isatin-type antibiotic with prominent activity against Bacillus subtilis, has been accomplished in 16% overall yield from 2-methylbut-3-en-2-ol and aniline via a five-step procedure. The protocol includes the aromatic aza-Claisen rearrangement and the Sandmeyer isonitrosoacetanilide isatin synthesis as key steps.
7-prenylisatin(一种对枯草芽孢杆菌具有显着活性的靛蓝型抗生素)的首次合成已通过5个步骤从2-甲基丁-3-烯-2-醇和苯胺以16%的总收率完成。该方案包括芳族氮杂-克莱森重排和Sandmeyer异亚硝基乙酰苯胺靛红合成的关键步骤。
