Synthesis of sildenafil and its derivatives bearing pyrazolo-pyrimidinones scaffold

초록

The pyrazole ring structure is extensively spotted as a pharmacophore and fortify-cation of the modern organic synthesis toolbox, which demands synthetic tactics to generate its derivatives. Especially, pyrazolo-pyrimidinones are crucial part to synthesize phosphodiesterase type 5 (PDE5) such as sildenafil and lodenafil. Herein, we report a simple and efficient route for Sildenafil and derivatives from easily available materials.
