Abstract
A pyridine catalyzed reaction between tetracyanoethylene and various activated CH-acid compounds to afford the corresponding pyran annulated heterocyclic ring systems in high yield at room temperature within a few minutes, is described. The work-up procedure is very simple and the products do not require further purification. © 2007 Elsevier B.V. All rights reserved.
