Solvent Free Condition

A simple and eco-friendly Montmorillonite K10 (MK10) catalyzed method for the synthesis of cyclopentenone derivatives from biomass-produced furfural has been developed. The versatility of this protocol is that the reactions were carried out in solvent free condition and in short reaction time under heterogeneous catalysis. Montmorillonite K10 is a material most explored as heterogeneous catalyst since it is inexpensive and environmentally friendly.
