An efficient and convergent first total syntheses of (±)-japonicol B and (−)-japonicol C have been completed. The notable points of the synthetic route are Lewis-acid-catalyzed Friedel–Crafts reaction for one pot C–C and C–O bond formations resulting in construction of the tricyclic meroterpenoid skeleton, one pot Pd(OH)2/C-catalyzed isomerization/hydrogenation, and site selective sp3 C–H oxidation
(±)-japonicol B和(-)-japonicol C的高效且收敛的首次全合成已经完成。合成路线的显着点是路易斯酸催化的弗里德尔-克拉夫茨反应,形成一锅 C-C 和 C-O 键,导致三环类萜骨架的构建,一锅 Pd(OH) 2 /C 催化异构化/氢化和位点选择性sp 3 C-H氧化。
