实验步骤: The vinyl sulfide of Example 4(a) (0.051 g) was irradiated in 20 mL of CH3OH containing ca. 1 mg of Rose Bengal with continuous oxygen bubbling at -78° C. using a 1000 W Na lamp. When the alkene was shown by TLC to be completely consumed, iodine (0.096 g) and 1 mL of 30% H2O2 were added and the mixture warmed to room temperature. Progress of the reaction was monitored by the disappearance of dioxetane 4 by TLC (20% ethyl acetate in hexane) and the appearance of new bands which emitted blue light when the plate was heated and by observing the color of chemiluminescence from an aliquot of the reaction solution reacted with 0.1 M TBAF in DMSO. The yellow emission of dioxetane 4 was gradually replaced by the blue emission of dioxetane 20 over a period of two hours. The solution was concentrated to 1-2 mL and separated on preparative TLC with 5% ethyl acetate in hexane. The band containing dioxetane 20 was collected and desorbed and evaporated to yield the product as a slightly yellow oil: 1H NMR (CDCl3) δ1.02 (m, 1H), 1.28 (m, 1H), 1.375 (s, 9H), 1.45-1.94 (m, 10H), 2.17 (br s, 1H), 3.04 (br s, 1H), 3.232 (s, 3H), 7.07-7.49 (m, 4H). to be completely consumed iodine (0.096 g) and 1 mL of 30% H2O2 were added was heated reacted with 0.1 M TBAF in DMSO The solution was concentrated to 1-2 mL separated on preparative TLC with 5% ethyl acetate in hexane The band containing dioxetane 20 was collected evaporated to yield the product as a slightly yellow oil
