A Ru-catalyzed direct oxidative coupling reaction of vinyl ketones was developed. It offers a straightforward and atom-economical protocol for the synthesis of functionalized (E,E)-1,6-dioxo-2,4-diene derivatives in moderate to good yields with excellent stereo- and chemoselectivities. In addition, the synthetic utility of this method was further demonstrated by its application to the synthesis of bioactive natural products such as (7E,9E)-henicosa-7,9-diene-6,11-dione (sex pheromone), ostopanic acid (plant anticancer agent), JA (anti-tumor agent) and the southern part (C1-C13) of the antibiotic macrolactin-T.
N-vinylpyridinium and -ammonium tetrafluoroborate salts: New electrophilic coupling partners for Pd(0)-catalyzed suzuki cross-coupling reactions

N-Vinylpyridinium and -trialkylammonium tetrafluoroborate salts represent a new class of electrophilic coupling partner for Pd(0)-catalyzed Suzuki cross-coupling reactions and give very good to excellent yields of products with a wide range of boronic acids. The salts are easily prepared from activated acetylenes and pyridinium or trialkylammonium tetrafluoroborates to form crystalline, air-stable, and nonhygroscopic crystals.
