title: Synthesis and ring expansions of functionalized spirocyclobutanones.
abstract: 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.
