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 کاملBrønsted acidic ionic liquid ([BMIm]HSO4) as an efficient catalysts for the one-pot synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives
The Brønsted acidic ionic liquid ([BMIm]HSO4) catalyzed three-component synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives at room temperature. The integrity of the ionic liquid remains reasonably unchanged when it is separated from the reaction mixture by water extraction, as it can be recycled several times without any loss of activity in each of the title syntheses. The products a...
