Substitution reactions of allylic alcohols 2 with various C-nucleophiles are described; in particular, 1,2-bis(trimethylsilyl)oxy)-cyclobutene in the presence of a Lewis acid leads to cyclobutanone derivatives which undergo an unusual acid-induced rearrangement affording spirocyclopropane structures.
