| Abstract: | A facile and efficient protocol for the synthesis of chromeno2,3-d]pyrimidinones and diazabenzob]fluorenones has been developed by one-pot three-component cyclocondensation of aldehydes, cyclic-1,3-diketones and 1,3-dimethylbarbituric acid in the presence of InCl3 or P2O5 under solvent-free conditions. |
