Synthesis of Dibenzocyclooctadienes by Anodic Oxidation
摘要:
Several lignoids with dibenzocyclooctadiene skeleton, such as schizandrins, domisins, schizantherins, stegans and kadsurins, have been reported to possess interesting biological activities (WAGNER, 1980: KUPCHAN, 1973) 1,2. Among them steganacin, isolated from Steganotaenia araliaceae Hochst., has been a synthetic target because of its antileukemic activity 2.

(−)‐Podophyllotoxin is one of the most potent microtubule depolymerizing agents and has served as an important lead compound in antineoplastic drug discovery. Reported here is a short chemoenzymatic totalsynthesis of (−)‐podophyllotoxin and related aryltetralin lignans. Vital to this approach is the use of an enzymatic oxidative C−C coupling reaction to construct the tetracyclic core of the natural
