Bronsted Acid Mediated Tandem Diels—Alder/Aromatization Reactions of Vinylindoles

摘要

A Bronsted acid catalyzed tandem Diels —Alder/aromatiza-tion reaction of 2-vinylindoles has been developed. Thereaction provides a highly efficient and concise approach to 3-indolyl-substituted tetrahydrocarbazoles with various sub-stituents in high yields under mild conditions.
