Biginelli-type heterocyclic compounds are particularly important due to their several chemical reactivities and various range of pharmacological activity. Therefore Biginelli reaction has witnessed modification numerous investigations continuing in this field develop more effective efficient methodologies. In research, Iron (III) schiff base immobilized SBA-15 been prepared as a valuable, efficient, recoverable catalyst for the reaction. The morphology was identified by spectroscopic characterization techniques structural microscopic analysis including Fourier transform infrared (FT-IR) patterns, X-ray diffraction (XRD) powder crystal method, Energy-dispersive spectroscopy (EDS) study, Thermogravimetric-Differential thermal (TGA-DTA), Transmission electron microscopy (TEM) Field emission scanning (FE-SEM) images. containing 3,4-dihydropyrimidines octahydroquinazolinones were conveniently synthesized catalyzed protocol from cycloaddition aromatic aldehydes with 1,3-dicarbonyl substrates urea via ultrasonic waves. advantages presented approach high yields easy isolation products, shorter times, milder conditions, stability reusable catalyst. combination heterogeneous radiation can make catalytic reactions than traditional ways attractive academic researchers application scholars industry.
