A novel, efficient, and scalable CO2 mediated synthesis of quinazoline-2,4(1H,3H)-dione was developed by a simple cyclization of 2-aminobenzonitrile with DMF in water as the solvent. This is the first report of its kind. DMF was used as the necessary carbon source in the synthesis of quinazoline-2,4(1H,3H)-dione. This synthetic protocol is very efficient; it gives >99% conversion with excellent selectivity

The synthesis of quinazoline-2,4(1H,3H)-dione was done by direct utilization of CO2 in the cyclization of 2-aminobenzonitrile (2-ABN) using lanthanum magnesia mixed oxide (La–Mg MO) as a strong basic catalyst under mild reaction conditions in water. It gave a conversion of ∼92% with 100% selectivity at 140 °C in 14 h. La–Mg MO was prepared by hydrothermal method using urea as homogeneous precipitating

Alogliptin is a potent, selectiveinhibitor of the serine protease dipeptidylpeptidaseIV (DPP-4). Herein, we describe the structure-based design and optimization of alogliptin and related quinazolinone-based DPP-4 inhibitors. Following an oral dose, these noncovalent inhibitors provide sustained reduction of plasma DPP-4 activity and a lowering of blood glucose in animal models of diabetes. Alogliptin
