The core structure of the natural product cyclodidemniserinol trisulfate, a natural HIV-1 integrase inhibitor, was synthesized by employing intramolecular ketal formation strategy via a convergent synthesis and a linear synthesis approach, respectively. Both approaches relied on Shapless asymmetric dihydroxylation to introduce the chiral centers at 1- and 7-position, and the latter also utilized Sharpless
通过分子内缩酮形成策略,分别通过聚合合成和线性合成方法,合成了天然产物环硫酸亚铁三醇,天然HIV-1整合酶抑制剂的核心结构。两种方法都依赖于无尖锐的不对称二羟基化作用以在1和7位引入手性中心,后者也利用Sharpless不对称环氧化将手性中心安装在3,5,7-三取代-6,8的3位上。 -二氧杂双环[3.2.1]辛烷。既定的方法学将有助于进一步的全合成和结构衍生化。
