Thiazolo-Pyrazole - derivatives
Opis:: 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 by varying the reaction parameters which includes use of different solvents and temperature. Synthesised compounds were characterised by different spectoscopic method such as 1H NMR, IR and Mass.

Opis:: A series of pyrano[2,3-b]indoles, was efficiently synthesized via one-pot, multi component reaction (MCRs) of 1,3-bifunctional synthon(malononitrile/ethylcyano acetate), aromatic aldehydes and oxiindole in the presence of various basic catalyst. The key advantages of this process are high yields, shorter reaction times, easy work-up, and purification of products by non-chromatographic method.

Opis:: A series of pyrimidine-5-carbonitrile derivatives was efficiently synthesized via one-pot, multi component reaction (MCRs) of 1,3-bifunctional synthon (ethylcyano acetate), substituted pyrazole-4-carbaldehyde, and thiourea/urea in the presence of basic catalyst. The key advantages of this process are high yields, shorter reaction times, easy work-up, and purification of products by non-chromatographic method.

Opis:: Pyrimidine related fused heterocycles are attracted to every chemist during the last decade for their biological and chemotherapeutic importance. Pyrimidine derivatives play a vital role in their broad spectrum of biological activities including antituberculosis, anticonvulsant, anti-inflammatory, insecticidal, antifungal, analgesic, and antitumor properties and there of interest as potential bioactive molecules. The nitrogen-containing fragment may be an amidine, urea, thiourea, or guanidine, and adamantine homologs and aromatic aldehyde serve as an excellent illustrative example in that it readily undergoes as Biginali MCRs reaction. Pyrimidines and their derivatives are considered to be important for drugs and agricultural chemicals. Pyrimidine derivatives possess several interesting biological activities. Pyrimidine is a basic nucleus in DNA & RNA, it is associated with diverse biological activities so, we have designed and prepared a novel highly functionalized pyrimidine library of 1,4 DHP and DHPM via a one-pot multi-component (MCRs) synthesis and we screened for antimicrobial activity against various strains.
