The first total synthesis of cristatic acid 1, an antibiotic endowed with considerable activity against Gram-positive bacteria, hemolytic properties, and significant cytotoxicity, is described. Key to success are the formation of its 2,4-disubstituted furan moiety via a palladium-catalyzed alkylation of vinylepoxide 10 derived from sulfonium salt 8 and the use of SEM ethers as the protecting groups
描述了具有抗革兰氏阳性细菌相当大的活性,溶血特性和显着的细胞毒性的抗生素-环酸1的第一个全合成。成功的关键是通过钯催化衍生自sulf盐8的乙烯基环氧化物10的2,4-二取代呋喃部分的形成,以及使用SEM醚作为酚OH官能团的保护基。
