A1 Sanz Díez, Roberto K1 Chemistry, Organic K1 Química orgánica AB Gold(I)-catalyzed cycloisomerization of β,β-diaryl-o-(alkynyl)-styrenes at 80 °C selectively yields dihydroindeno[2,1-a]indenes in atransformation that encompasses a formal [4 + 1] cycloaddition and takesplace through a cascade 5-endo-cyclization−diene activation−iso-Nazarovcyclization. In addition, by performing the reaction at 0 °C, the samesubstrates exclusively give rise to benzofulvene derivatives, which have also been shown to be intermediates in the formation ofthe tetracyclics.
