Abstract
In the presence of a 1,2-bis(diphenylphosphino)ethane-cobalt(II) chloride-zinc catalyst in 1-methylpyrrolidin-2-one at room temperature to 50 ˚C, α,ω-diynes reacted with nitriles by a [2+2+2] cycloaddition pathway to give annulated pyridines or 2,2′-bipyridines. The regioselectivity of the reaction is controlled by a combination of steric and electronic effects. The reaction of diynes with a terminal trimethylsilyl group gave the corresponding 3-(trimethylsilyl)pyridines exclusively; these products could be proto- or halodesilylated to give the corresponding protonated or halogenated pyridines or 2,2′-bipyridines.
Key words
