Abstract

Driven by the need of structural modification to establish structure-activity relationships, the regioselective C–H bond activation of thiazolo[5,4-f]quinazolin-9(8H)-one backbone has been developed to furnish the corresponding C2-arylated valuable scaffold. This strategy provides a synthetically streamlined and useful route for late-stage diversification of this attractive skeleton, required in drug discovery. A more eco-friendly synthesis of thiazolo[5,4-f]quinazolin-9(8H)-ones is also described giving access to these aforementioned compounds in a facile manner.
