Free radical ring-expansion of a variety of heterocycles is described. The regioselective, free radical ring-expansion of P-keto esters1p2r3 has broad potential applicability in organic synthesis. 4 The synthetic utility of the ring-expansion reaction will be further enhanced by the inclusion of he

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
