The lactonization of ω-hydroxy esters was carried out by catalysis with hydrous zirconium(IV) oxide.In the flow reaction system, ω-hydroxy esters were efficiently converted to give the corresponding lactones.In particular, it is noteworthy that heptanolide is obtained in good yield.In addition, it is possible to produce a large quantity of lactones in this catalyst system.
