英文摘要	Photochemically generated singlet oxygen adds selectively to c-20-c-22 rather than c-5-c-6 double bond of pseudodiosgenin diacetate 1 to give diosone 4, an important intermediate for preparation of many steroidal drugs, and ene product 3 at room temperature. 3 was separated and characterized by h-1 and c-13 nmr as well as ir. when pyridine and acetic anhydride were presented, the criegee rearrangement of 3 can yield 4, as a result, leading to a high collection yield (80% in acetonitrile) of 4.
