Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A development of Groebke-Blackburn-Bienaymé (GBB) reaction was shown by the application of Etidronic acid as a green catalyst. The title compounds were prepared via multicomponent GBB reaction in one pot sequential steps by the condensation of 2-amino-1H-pyrazol, aldehyde and isonitrile. Here, we have demonstrated the development of GBB protocol by the utility of Etidronic acid in milder reaction medium to modify and simplify the existing synthetic strategies that removes hazardous acids, toxic solvents and drastic conditions with sustainable product yields and purity. 88 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A novel [1,2,4]triazolo[4,3-c]pyrimidine-8-carboxamide libraries were synthesized via oxidative cyclization of hydrazono-1,6-dihydropyrimidine-5-carboxamide intermediates by the application of Iodobenzenediacetate as a sole cyclizating agent. Here, we report one pot sequential strategy to generate corresponding triazolopyrimidines by condensation of preprepared -acylketene dithioacetals and arylamidines. Moreover, this process describes the application of presynthesized arylamidines which omits the transition metal catalyzed Suzuki-Miyaura cross coupling reaction hence signify the atom- and step-economic methodology. 88 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Synthetic studies of fused pyrimidine have been reported extensively because of their structural diversity and association with a wide spectrum of biological activity. It has been observed over the years that poly substituted pyrimido[1,2-a]benzimidazoles possess a wide spectrum of biological activities and they are structurally related to natural purine bases. With this background we have prepared a library of imidazopyrimidine analogues by one pot Biginelly type multi-component reaction. The process has several advantages like neat reaction and easy workup and purification steps. All the synthesized compounds were evaluated for their antimicrobial activity. The investigation of antimicrobial and anti-fungal screening data revealed that all the tested compounds showed moderate to significant activity. 80 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Pyrimidine is a well known hetero-cyclic compound, which has been subjected to a large variety of structural modification in order to synthesize derivatives with different biological properties. Pyrimidine derivatives have been reported to possess a broad spectrum of pharmacological properties. Pyrimidine is the most important member of all the diazines as this ring system occurs widely in living organisms. Purines, uric acid, barbituric acid and some anti-malarial and anti-bacterial agents also contain the pyrimidine ring. 56 pp. Englisch. …
