Abstract:	Direct chemoselective oxidation of δ-lactones via highly stable benzyl radical cyclization is reported. The one-pot conversion of premade substituted 5-aryl pentanoic acid and 8-benzyl-1-naphthoic acid in the presence of K₂S₂O₈–CuCl₂ results to the δ-lactones in moderate to good yields. The advantages of this methodology is using water as a solvent and utilizing available starting materials.

Keywords:	δ -Lactones Benzyl radical Chemoselective oxidation K₂S₂O₈– CuCl₂
