متن کاملEco-Friendly and One-Pot Synthesis of 1,8-Dioxooctahydroxanthene Derivatives Catalyzed by Task-Specific Brønsted Acidic Ionic Liquid
Efficient and one-pot synthesis of 1,8-dioxo-octahydroxanthenes was described by Knoevenagel condensation, Michael addition and cyclodehydration of dimedone. This reaction was carried out through condensation of dimedone and various aromatic aldehydes in the presence of task-specific Brønsted acidic ionic liquid under solvent free conditions. The catalyst could be recycled five times without si...

متن کاملThe green synthesis of pyrano[3,2-c]quinoline-2,5-dione derivatives catalyzed by acidic ionic liquid under ultrasound irradiation
Abstract-A novel and efficient method has been developed for the synthesis of pyrano[3,2-c]quinoline-2,5-dione derivatives by the convenient ultrasound-mediated condensation of 4-hydroxyquinolin-2-one with Meldrum’s acid and aldehydes in the presence of a catalytic amount of [HMIm]HSO4 as a green, efficient and reusable acidic ionic liquid medium. The stability of the ionic liquid during the re...
