By treatment with BF3/ethyleneglycol, cyclopentanones with the carbonyl function at the C3-position of a-side chain undergo the ring cleavage to build up the seven membered rings, and this novel ring expansion was applied to the synthesis of bulnesol. Recently, we have reported the new type fragment
