title: Ruthenium-catalyzed synthesis of functionalized dienes from propargylic esters: formal cross-coupling of two carbenes.
abstract: Cross-coupling carbenes: The coupling of a propargylic ester with a diazoalkane in the presence of [RuCl(cod)Cp*] catalyst leads to the formation of functionalized conjugated dienes with high stereoselectivity. The reaction involves the cross-coupling of a vinylcarbene fragment, arising from a ruthenium-catalyzed propargylic ester rearrangement, with a diazoalkane carbene.
