Ring-closing metathesis of ene-ynamide, which has alkene and ynamide moieties in a molecule, using a second-generation ruthenium carbene complex produced nitrogen-containing heterocycles, which have a dienamide moiety, in high yields. Diels-Alder reaction of the cyclized product with dienophile proceeded smoothly to give an indole or quinoline derivative in high yield. (c) 2006 Elsevier Ltd. All rights reserved.
