RESUMEN
A BF3-mediated domino dehydration/electrophilic cyclization of silylalkynols to form 2,3-fused tricyclic benzofulvenes was achieved. In the latter step, in situ generated BF3·OH2 enables the electrophilic activation of alkynes. The predominant Z-selectivity of the reaction is also discussed.
