efficient synthesis of fused nitrogen heterocycles containing various combinations of five- and eight-membered rings has been developed. This method features the ring-closingmetathesis (RCM), which is catalyzed by the molybdenumalkylidenecomplex 6, of α,ω-dienes that have a nitrogen atom in the chain linking the two olefinic functional groups.
