eco-friendly and one-pot synthesis of 1,8-dioxooctahydroxanthene derivatives catalyzed by task-specific brønsted acidic ionic liquid
Authors
abstract
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 significant loss of its catalytic activity.
