Aspartic acid supported on montmorillonite K10: A novel and green heterogeneous catalyst for the synthesis of xanthenediones under solvent-free conditions

A green and efficient procedure for the synthesis of xanthenedione derivatives is described through a one-pot condensation of aryl aldehydes and dimedone in the presence of aspartic acid supported on montmorillonite K10 under solvent-free conditions. The developed procedure has some advantages such as using a green and efficient catalyst with high catalytic activity, clean process and easy workup.
