Synthesis of Cyclopentacarbazolones via Palladium-Catalyzed Annulation of Internal Alkynes
Publication History
Publication Date:
27 March 2012 (online)
Abstract
A simple and efficient protocol for the synthesis of highly substituted cyclopentacarbazolones (50-82%) was developed by employing internal alkynes with 2-bromo-3-formylcarbazoles in the presence of palladium catalyst under ligand-free condition. High regioselectivity was observed for unsymmetrical (alkyl-, aryl-substituted) internal alkynes.
Key words
estrogen receptors - palladium catalyst - annulations - cyclopentacarbazolones - ligand-free synthesis
