Cobalt(II)-Catalyzed Intermolecular Diels−Alder Reaction of Piperine

, 2016
An intermolecular cobalt−phosphine-catalyzed Diels−Alder reaction of piperine is described. The dimerization of piperine in the presence of cobalt−phosphine complexes gave much better yields than that in the presence of only cobalt, which, combined with ...
