Palladium-catalyzed cycloisomerisation reaction of 1,6-enyne acetic esters to form five-membered nitrogenated heterocyclic conjugated trienes
A palladium-catalyzed cycloisomerisation reaction of 1,6-enyne acetic esters have been developed. This cyclization reaction shows excellent regioselectivity and good functional group tolerance to obtain five-membered nitrogenated heterocyclic conjugated t
Palladium-catalyzed divergent reactions of 1,6-enyne carbonates: Synthesis of vinylidenepyridines and vinylidenepyrrolidines
A method for preparing five- or six-membered heterocyclic compounds from enyne carbonates via palladium catalysis was developed. Enyne carbonates were transformed into 3-vinylidene-1-tosylpyridines 2 in the presence of PdI 2 as the catalyst. Us
