A convenient and efficient synthesis of 2-thio-5-hydroxy-5H-[1]benzopyrano[4,3-d] pyrimidines via ultrasonic irradiation compared with conventional method
We report an easy and powerful approach to the synthesis of 2-thio-5-hydroxy-5H-[1]benzopyrano[4,3-d] pyrimidines derivatives by condensation of 3-Formylchromone and thiourea under conventional heating and ultrasonic irradiation. The ultrasonic irradiation is convenient and efficient method as compa...
