چکیده مقاله :
Various substituted coumarins were synthesized in high yield and purity by direct reaction of substituted phenol and β-keto esters in the presence of a catalytic amount of salicylic acid under solvent-free conditions. This method is simple, cost-effective, short reaction time, simple work-up procedure, and avoid the use of transition metals.
