The acid-catalyzed self-condensation reaction of b-diketones in the presence of 2,2,2-trifluorodiazoethane
… acid-catalyzed self-condensation reaction of 6-diketones in the presence of 2,2,2-trifluorodiazoethane (TFD) has been discovered. This reaction is of interest because not many methods are available for the preparation of cyclized products (e.g., aromatic natural products) from 6-dicarbonyl …
