Abstract
An efficient decarboxylative cycloaddition of 2,3-dioxopyrrolidines and ethynyl
benzoxazinanones has been established by cooperative copper/amine catalysis. A copper–
allenylidene complex and enolate intermediate, each catalytically generated from distinct
substrates, underwent a cascade propargylation/hydroamination/aromatization process to
construct a big library of cyclopenta[b]indole derivatives with good to excellent yields and
excellent diastereoselectivity.
