Article abstract of DOI:10.1016/S0040-4039(00)82030-4

By treatment with BF3/ethyleneglycol, cyclopentanones with the carbonyl function at the C₃-position of α-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.
