Özet

The [Cu(acac)(2)]-catalyzed reactions of alpha,beta-unsaturated carboxamides with dimethyl diazomalonate yielded dihydrofuran derivatives by a 1,5-electrocyclic reaction at C(beta), and butadiene derivatives by carbene addition reaction at C(alpha) (Schemes 4 and 5; Table). Phenyl substituents at the N-atom of the amides seem to be effective on the reaction pathways (Table).
