Recent developments in the synthesis of tricyclic condensed pyrimidinones.

Functionalized tricyclicpyrimidinones, a class of condensed heterocyclic systems, are found in numerouspotentially active molecules having both innate as well as synthetic origin. Different researchers across the world have explored different synthetic methods for the construction of appropriately functionalized tricyclicpyrimidinones. The present review article recapitulates various reports pertaining to substituted and functionalized tricyclic pyrimidinones reported since 2000. [ABSTRACT FROM AUTHOR]
