Re2(CO)10 or Yb(OTf)3 afforded 2H-pyran-2-one derivatives or α,β-unsaturated ketones in moderate to good yields through a highly regioselectivecarbon–carbonbondcleavage pathway. The substituents at the cyclopropane mainly determine the regioselectivity of the carbon–carbonbondcleavage, providing different products of tandem ring-opening and rearrangement reactions.
