Microwae-Assisted One-Pot Three Component Synthesis of Some New 4(3H)-Quinazolinone Derivatives

摘要

Efficient microwave-assisted synthesis of 4(3H)-quinazolinones by the one-pot three-component condensation of isatoic anhydride,primary amines and orthoesters in the presence of catalytic amounts of p-toluenesulfonic acid in high yields is reported.
