A novel and efficient procedure for the generation of quinazolinone phosphonate derivatives employing the reaction of euparin, isatin or
its derivatives, primary amines, dialkyl acetylenedicarboxylates, trimethyl phosphite or triphenyl phosphite, and acidic solution of hydrogen peroxide in aqueous media at ambient temperature under ultrasonic irradiation was developed. Without ultrasonic irradiation, the reaction does not proceed and agitation of the reaction mixture is difficult. Some advantages of this procedure are: short time of reaction, high yields of products, easy isolation of products.
