mimicking the naturally occurring hydrophilic steroids is of topical interest. In the present work, a D-secoestrone derivative was modified further by Barbier-allylation - ring-closing metathesis - dihydroxylation sequence with the aim to prepare steroid based structures with limited hydrophilicity. A straightforward synthesis route was developed with the isolated yield for each step ranging from good
多羟基化的类固醇,例如油菜素类固醇、植物蜕皮类固醇和类固醇皂苷,是结构上有吸引力的化合物,具有许多有趣的生物学特性。因此,开发合成程序以构建模拟天然存在的亲水性类固醇的基于类固醇的结构是局部感兴趣的。在目前的工作中,通过 Barbier-烯丙基化 - 闭环复分解 - 二羟基化序列进一步修饰 D-癸烯雌酮衍生物,目的是制备具有有限亲水性的基于类固醇的结构。开发了一条简单的合成路线,每个步骤的分离产率从好到极好。制备的所有化合物均通过 NMR 光谱技术进行了充分表征,并在本文中报告了完全指定的 (1) H 和 (13) C 光谱。最后,
