Synthesis of New Pyrazole Derivatives Using Vinamidinium Salts
Novel pyrazole derivatives 2-7 are synthesized by the reaction of 2-substituted 1,3-bis(dimethylamino)-trimethinium salts with phenyl hydrazine in acetonitrile as the solvent. This method has some advantages of high yields (78-85%), simplicity of the process and easy of control. The ultraviolet spectral behavior of the synthesized compounds is examined in CDCl3 and their structures were charact...
متن کاملOne-pot synthesis of 1,3-benzo[d]thiazole derivatives promoted by Al(HSO4)3 under sonication conditions
The presence of an imidazole ring in natural products and pharmacologically active compounds has instituted a diverse array of synthetic approaches to these heterocycles. Very recently, we among many others have demonstrated that heterogeneous reagent systems have many advantages such as simple experimental procedures, mild reaction conditions and minimization of chemical wastes as compared to ...

متن کاملFrom Pyrylium to Pyridinium Salts: Understanding Physicochemical Features
It is known that physical properties of pyridinium salts can be modulated by their chemical characteristics. Owing to their broad range of applications in biology, biotechnology and chemical research, the design and synthesis of a series of 2,4,6-triarylpyridinium salts with modified structural backbone have been carried out. The main strands of work have included modifications on pyrylium cati...
