BF3·OEt2-promoted intramolecular nucleophilic substitution; Synthesis of dibenzopyranones and coumarins from biaryltriazenes

A simple and highly efficient reaction promoted by Lewis acid has been demonstrated for the synthesis of dibenzopyranones. The metal-free annulation can tolerate a series of functional groups and also allows the synthesis of coumarins and phenanthridinones in good to excellent yields. The synthesis of coumarins through BF3·OEt2-promoted intramolecular nucleophilic substitution has been demonstrated. The efficient synthetic methodology provides good to excellent yields of dibenzopyranones and phenanthridinones. Copyright
