摘要

Summary: Singlet oxygen reacts with 1-acetyl-Z-methoxycyclopentene (la) to give the unsaturated hemiperketal 3a. the epoxy-B-diketone% 3a decomposes by an intermolecular oxygen atorn transfer to give-* Several S-alkoxyenones which are held in the s-trans conformation failed to react with singlet oxygen.
