Pyranopyrandiones were prepared by a novel ruthenium-catalyzed carbonylative dimerization of cyclopropenones via C-C bond cleavage. For example, treatment dipropylcyclopropenone with catalytic amount Ru3(CO)12 and NEt3 in THF under 15 atm carbon monoxide at 140 degrees C for 20 h gave functional monomer, 3,4,7,8-tetrapropylpyrano[6,5-e]pyran-2,6-dione, an isolated yield 81%. Unsymmetrically substituted pyranopyrandiones also obtained coupling alkynes similar reaction conditions.
The zero-valent ruthenium complex (η6-1,3,5-cyclooctatriene)bis(η2-dimethyl fumarate)ruthenium effectively catalyzes the highly selective codimerization of N-vinylamides with alkenes or alkynes and was successfully applied in cotrimerization ethyl acrylate ethylene (see scheme). These reactions offer a rapid atom-economical synthesis biologically synthetically important enamides dienamides.
