Enantiomerically pure 5-acetoxy-2(5H)-furanone and 6-acetoxy-2H-pyran-3(6H)-one are converted into 5-alkoxy-2(5H)-furanones and 6-alkoxy-2H-pyran-3(6H)-ones by a palladium catalyzed allylic substitution. The reactions proceed with nearly complete retention of configuration, resulting in products with ee's of 95%.
