β-Lactone precursors 11 and 12 of pyramidalizedalkenes 3,n = 1and 2, have been synthesized by a two-step route involving transannular Paterno-Buchi reaction of methyleneketones 7 and 8, followed by RuO4 oxidation of the resulting oxetanes 9 and 10. Evidence for the formation of alkene 3,n = 2, by pyrolysis of 12 is presented.
