An easily reproducible protocol allowing inter- or intramolecular spirocyclization on beta-dicarbonyl structures is described. This methodology could afford a wide variety of spirocyclic pharmacophores. As examples, highly substituted spirobenzophenanthridin-6(5H)-ones and spirolactones were synthesized. These scaffolds could be used for the design of many compounds exhibiting biological activities. (C) 2012 Elsevier Ltd. All rights reserved.
