A facile one-pot synthetic route for preparing the novel benzofused tricyclic skeleton of 1,2,2a,8b-tetrahydrocyclobuta[a]naphthalenes 5 is developed. The route was realized by a NaH-mediated tandem aldol condensation/olefin migration/electrocyclization of o-allylbenzaldehydes 1 with cinnamyl sulfones 3 in good yields.

An easy and straightforward synthesis of 6,10b-diarylhexahydrobenzo[f]isoquinoline by the repeated treatment of boron trifluoride etherate (BF(3) x OEt(2)) is reported. The overall transformation from 4-arylpiperidin-3-one to benzo[f]isoquinoline proceeds via ring contraction, chain elongation, and intramolecular electrophilic cyclization in moderate yields. It presents a novel rearrangement reaction catalyzed by boron trifluoride etherate and broadens the scope of application.
