Abstract: A series of triazolyl-modified podophyllotoxin analogs have been designed and synthesized by utilizing Huisgen 1,3-dipolar cycloaddition in order to develop potent antitumor agents. The synthesized analogs were assessed for in vitro anticancer a

An efficient nickel(ii)-catalyzed transfer dehydrogenation oxidation of alcohols is reported that relies on cyclohexanone as the formal oxidant and does not require the use of an external base. The synthetic utility of this protocol is demonstratedviathe facile oxidation of structurally complicated natural products.

(?)-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 total synthesis 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 product in a diastereoselective fashion. This strategy allows gram-scale access to (?)-deoxypodophyllotoxin and is readily adaptable to the preparation of related aryltetralin lignans.
