Rapid Access to Polyprenylated Phloroglucinols via Alkylative Dearomatization−Annulation: Total Synthesis of (±)-Clusianone
摘要:
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.
