A C-C bond cleavage/vinylation/Mizoroki-Heck cascade reaction has been developed to provide access to densely functionalized bicyclo[2.2.2]octane frameworks. The sequence proceeds through the coupling of dihydroxylated pinene derivatives, prepared from carvone, with -dichloroalkenes. The method was applied to 12-step total syntheses of both 14- and 15-hydroxypatchoulol, which provided unambiguous support for the structure of the natural products and corrects a misassignment in the isolation report.
发展了 C-C 键断裂/乙烯基化/Mizoroki-Heck 级联反应，以提供获得稠合官能化双环[2.2.2]辛烷骨架的途径。该序列通过与二氯代烯烃的耦合进行，所述二氯代烯烃由香芹酮制备得到。该方法应用于 14-和 15-羟基对盖醇的 12 步全合成，为天然产物的结构提供了明确的支持，并纠正了分离报告中的错误分配。
