A variety of schiff base of 3-amino-2,7-dimethyl-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-4(3H)-one have been synthesized using novel and yield efficient protocol i.e., Gewald condensation reaction by four step processes. The characterization of synthesized diverse molecules was characterized by various spectroscopic methods such as IR, Mass, and NMR. The hybrids of thieno-pyrimidines were...
Knowing the importance of thiazole and pyrazole ring systems in various useful natural products and based on the reported biological activities of the synthetic derivatives of these ring system containing compounds against different types of microbes, we have synthesized novel thiazolo - pyrazole derivatives by one pot multi component catalyst free synthetic method. The product yields have been optimized...
