We report a concise chemical synthesis of kalihinol C via a possible biosynthetic intermediate, "protokalihinol", which was targeted as a scaffold en route to antiplasmodial analogs. High stereocontrol of the kalihinol framework relies on a heterodendralene cascade to establish the target stereotetrad. Common problems of regio- and chemoselectivity encountered in the kalihinol class are explained and
我们通过可能的生物合成中间体“protokalihinol”报告了 kalihinol C 的简明化学合成,该中间体被定位为抗疟原虫类似物的支架。kalihinol 框架的高度立体控制依赖于异树烯级联来建立目标立体四分体。解释并解决了 kalihinol 类中遇到的区域选择性和化学选择性的常见问题。
