Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In a patent, 4865-84-3, molecular formula is C9H7NO3, introducing its new discovery. Safety of 1,2-Benzisoxazole-3-acetic Acid
Synthesis and antimicrobial studies of novel methylene bridged benzisoxazolyl imidazo[2,1-b][1,3,4]thiadiazole derivatives
Novel methylene bridged benzisoxazolyl imidazo[2,1-b][1,3,4]thiadiazoles (3a-f) were synthesized from benzisoxazolyl-3-acetic acid and thiosemicarbazide. Reaction of 3 with bromine in glacial acetic acid in the presence of anhydrous sodium acetate yielded the corresponding 5-bromo derivatives (4a-f). While compound 3 furnished the 5-nitroso derivatives (5a-f) on refluxing with sodium nitrite solution. Thiocyanato derivatives (6a-f) were obtained by treating the imidazothiadiazole 3 with bromine and potassium thiocyanate in glacial acetic acid at room temperature. The structures of the newly synthesized compounds were confirmed by IR, NMR, mass and elemental analysis. All the compounds were screened for their antibacterial and antifungal activities. Some of the compounds displayed very good antibacterial and antifungal activity.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to Safety of 1,2-Benzisoxazole-3-acetic Acid, help many people in the next few years.Safety of 1,2-Benzisoxazole-3-acetic Acid
