A gold(I)-catalyzed intramolecular tandem cyclization reaction of alkylidenecyclopropane-containing alkynes

Author affiliations

Abstract

A novel gold(I)-catalyzed intramolecular tandem cyclization reaction of ortho-(arylethynyl)arenemethylenecyclopropanes provided an efficient approach to prepare functionalized 11H-benzo[a]fluorene derivatives in moderate to good yields. Further transformations as well as applications of the products have been presented and a plausible reaction mechanism has also been proposed on the basis of deuterium labeling and control experiments.
