An ultrasound assisted cyclocondensation reaction for the efficient synthesis of [1]benzopyranopyrido[d]pyrimidines using porous graphene/MoO3
In this paper, we report a feasible protocol for the preparation of [1]benzopyranopyrido[d]pyrimidines via expeditious sonochemical route. The reaction efficiency was evaluated by influence of several parameters including sonication power, sonication time, different solvents, and using porous graphene/MoO3 nanocomposite as catalyst, for the first time. The effect of the ultrasonication comparing with the conventional heating on the synthesis of the titled compounds shows that the ultrasonic irradiation is required to rich the cyclized products. The structural properties of porous graphene/MoO3 nanocomposite were determined by Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffractometry (XRD), scanning electron microscope (SEM), Raman spectroscopy, and also by TGA analysis. Confirmation of the structures of compounds 4a-4h were also established with IR, H-1 NMR, and C-13 NMR spectroscopic data and also by elemental analyses.
