A Concise Enantioselective Approach to Quassinoids

open access: yesJournal of the American Chemical Society, 2021
A synthetic approach to quassinoids is described. The route to the tetracyclic core relies on an efficient and selective annulation between two unsaturated carbonyl components that is initiated by catalytic hydrogen atom transfer from an iron hydride to an alkene.
