Melamine trisulfonic acid as an efficient and reusable catalyst for the crossed-Aldol condensation of ketones and aldehydes under solvent-free conditions
Various types of aldehydes undergo crossed-Aldol condensation with ketones in the presence of melamine trisulfonic acid (MTSA) under solvent-free conditions. The reported method is mild, efficient and has the advantages such as using heterogeneous catalysis, short reaction times, high yields of the products and the recyclability of the catalyst.

متن کاملMelamine Trisulfonic Acid as a New, Efficient and Reusable Catalyst for the Solvent Free Synthesis of Coumarins
Coumarins and their derivatives are important classes of heterocyclic compounds whose synthesis has been the focus of attention of many organic and medicinal chemists. Such an interest in these compounds can be attributed to their variety of bioactivities such as, inhibition of platelet aggregation [1], antibacterial [2], anticancer [3], inhibitor of steroid 5αreductase [4] and inhibitor of HIV...
