Abstract
Vinyl sulfides bearing protected arlyoxy substituents and a process for their preparation are provided. In the process a vinyl sulfide is formed by coupling a ketone compound and a thioester compound with a low valent titanium reagent to form both carbon-carbon bonds in the same step. The vinyl sulfide compounds are useful as intermediates which are convertible into triggerable sulfur-substituted dioxetanes by addition of oxygen to the double bond. The sulfur-substituted dioxetanes additionally are useful for producing chemiluminescence or for further conversion into triggerable alkoxy, alkenyloxy, alkynloxy, aryloxy, aralkyloxy, or acyloxy-substituted dioxetanes. Triggerable dioxetanes are useful for producing chemiluminescence and in detecting activating agents in assays such as immunoassays and nucleic acid hybridization assays.
