ASPARTIC ACID SUPPORTED ON MONTMORILLONITE K-10 CATALYZED SYNTHESIS OF XANTHENEDIONES

Xanthene and their derivatives are an important group of organic compounds owing to their extensive range of biological and pharmacological activities. Aspartic acid supported on montmorillonite K-10 is successfully used as efficient heterogeneous catalyst for the synthesis of xanthenediones by one pot condensation of dimedone with aryl aldehydes under solvent-free conditions. In this method, we used nanocatalyst for producing products in excellent yields and short reaction time without using organic solvents. This procedure has some advantages such as using a green and efficient catalyst with high catalytic activity, clean process and easy workup
