first total synthesis of (+)-thiazinotrienomycin E (1), member of a novel class of cytotoxic ansamycin antibiotics, has been achieved. Key features of the synthetic strategy include (a) the efficient construction of sulfone 7 incorporating TBS protection of the aniline, (b) an improved synthesis of allyl chloride (-)-6, the advanced intermediate employed in our trienomycins A and F total syntheses, (c)
已实现(+)-thiazinotrienomycin E(1)的首个全合成,这是新型细胞毒性安沙霉素抗生素的成员。合成策略的关键特征包括:(a)结合苯胺的TBS保护有效构建砜7,(b)改进烯丙基氯(-)-6的合成,这是我们的曲安霉素A和F总合成中使用的高级中间体,(c)应用Kocienski修改后的Julia协议以立体控制的方式修饰E,E,E-三烯亚基,(d)砜7与高级碘化物62的有效结合,以及(e)Mukaiyama大内酰胺化为访问thiazinotrienomycin大环。
