متن کاملSynthesis of Benzopyrano[2,3-d]pyrimidines Using Silica-Bonded N-Propyldiethylenetriamine Sulfamic Acid (SPDTSA) As Heterogeneous Solid Acid Catalyst under Solvent-Free Conditions
Silica-bonded N-propyldiethylenetriamine sulfamic acid (SPDTSA) is employed as a recyclable heterogeneous solid acid catalyst for the synthesis of benzopyrano[2,3-d]pyrimidines through one-pot condensation reaction of salicylaldehydes, malononitrile and secondary amines at room temperature under solvent-free conditions. SPDTSA showed much the same efficiency when used in con...

متن کاملMicrowave-assisted thioacetalization of carbonyl compounds using Al-MCM-41 as an efficient heterogeneous catalyst
In this project various types of carbonyl compounds were efficiently converted to their corresponding 1,3-oxathiolanes with 2-mercaptoethanol in the presence of catalytic amount of Al-MCM-41 with microwave energy. The catalyst can be reused several times without loss of its catalytic activity. Very short reaction times, reusability of the catalyst, and easy workup are noteworthy advantages of ...
