Preparation And Evaluation Of The Biological Activity Of A 2- Amino Pyran Ring Using A Solid Base Catalyst

The research included preparing a basic catalyst by reacting potassium nitrate with alumina to produce the heterogeneous solid basic catalyst and then introducing the catalyst as a catalyst in preparing the 2-amino pyrane ring by reacting the prepared chocolate with malononitrile and using only stirring without sublimation or heating. The compositions were validated using physical measurements such as percentage, melting point, and colour and spectroscopic measurements such as proton and carbon nuclear magnetic resonance and infrared spectra. The nanoscale size of the catalyst was also confirmed by scanning electron microscope (SEM) analysis. Two types of positive bacteria were used—gram and gram-negative to verify biological activity.
