【 摘 要 】

A highly efficient and practical approach for the synthesis of novel heterocyclic bis-chalcones and corresponding pyrazolines has been developed using cellulose sulfuric acid as environmentally benign, biodegradable and reusable catalyst under solvent-free conditions. The catalyst can be reused several times without significant loss of its catalytic activity.
