A new route to γ-substituted γ-lactones and δ-substituted δ-lactones based on the regioselective β-scission of alkoxyl radicals generated from transannular hemiacetals
A new general synthesis of γ-substituted γ-lactones and δ-substituted δ-lactones including dihydro-5-octyl-2(3H)-furanone, a natural pheromone, is described. The synthesis involves the regioselective β-scission of alkoxyl radicals generated from transannular hemiacetals as the key step.
