A biomimetic approach toward type A polyprenylated acylphloroglucinols (PPAPs) is described. The method is based on a C-alkylation−cation cyclization reaction sequence, leading to a convenient buildup of molecular complexity, employing the simple and readily available deoxycohumulone and an appropriately functionalized hydroxy halide. Thus, a versatile construction of the fully functionalized bicyclic

hydroalumination of methyl propiolate and Lewis-acid-promoted reaction with acetone in the presence of BF3 followed by two highly selective SN2′ reactions. The key step is the reaction of 2-(chloromethyl)acrylates with R2CuLi/ZnCl2 reagents which takes place with complete allylic rearrangement.
标题产物是通过有效的三步合成法制备的,该方法包括丙三酸甲酯的氢铝化和在BF 3存在下与丙酮进行路易斯酸促进的反应,然后进行两个高度选择性的S N 2'反应。关键步骤是2-(氯甲基)丙烯酸酯与R 2 CuLi / ZnCl 2试剂的反应,该反应在完全烯丙基重排的情况下进行。

A concise approach to the bicyclo[3.3.1]nonane framework of the polyprenylated phloroglucinol natural products utilizing a tandem alkylative dearomatization-annulation sequence is described. Syntheses of (+/-)-clusianone and a complex adamantane framework have been achieved using the developed methodology.
