One Pot Synthesis

A rapid and efficient one-pot method for the synthesis ofβ-acetamido ketones/esters has been developed in the presence of bulk tungstophosphoric acid and its supported forms on activated carbon as recyclable and eco-friendly catalysts under refluxing conditions. Supported tungstophosphoric acid catalysts containing the same amount of heteropoly acid yielded much higher conversion than bulk form.

In this study, a rapid and convenient synthesis of quinolines was developed. The reaction involves a one-pot synthesis of pyranoquinoline derivatives from aldehyde, malonitrile, and 8-hydroxyquinoline using DABCO as a catalyst at 80 °C in H2O/EtOH as the solvent in good to high yields.
