Abstract

A highly practical and efficient preparation of pyrano[3,2-c]pyridone and pyrano[4,3-b]pyran derivatives was developed via an ionic liquid mediated and promoted multi-component reaction of aldehyde (1), 4-hydroxy-pyridin-2(1H)-one or 4-hydroxy-2-pyranone (2), and malononitrile (3). As an application, a series of pyrimidine nucleoside-pyrano[3,2-c]pyridone or pyrano[4,3-b]pyran hybrids were efficiently obtained. These hybrid compounds were evaluated as potential Antiviral and antileishmanial agents and showed encouraging biological activities.
