A novel and generally applicable approach to A-ring aromatic trichothecane 2 was achieved by the regiocontrolled cyclization of 25, 26, 29, and 30 as a key step, followed by stereoselective construction of the epoxide ring. This manuscript also described the regiocontrolled ring expansion of the olefinic cyclobutanols 19–22 to give the enones 23 and 24 which were the important intermediates in this
通过将25、26、29和30的区域控制环化作为关键步骤,然后立体选择性地构建环氧环,可以实现一种新颖且普遍适用的A环芳族三硫杂环丁烷2的方法。该手稿还描述了烯属环丁醇19-22的区域控制环扩展,得到了烯酮23和24,它们是该方法的重要中间体。
