摘要: Abstract Efficient synthesis of 7-aminocoumarins was performed via the Pechmann reaction by microwave irradiation reactants on solid support (graphite/montmorillonite K10). In this convenient new methodology, strong thermal effect due to graphite/microwaves interaction is associated with acidic catalyst role clay.
