Geminal acylation of omega-acetylenic acetals and bis(silyloxy)cycloalkenes under Lewis acid conditions preceded cationic cyclization of the alkyne onto the ketone to produce polycyclic unsaturated ketones.

The first condensations between bis(trimethylsilyloxy)cyclobutene derivatives and functionalized orthoesters are reported. The resulting adducts are readily converted into spirocycloethers, which undergo a variety of -CH2- and -O- insertions with excellent regioselectivity.
