The synthesis of bis(1,2,4-oxadiazoles), 1,2,4-oxadiazolyl-quinazolines, and 1,2,4-oxadiazolyl-benzothiazinones has been investigated by the reaction of diaminoglyoxime with various ketones and methyl 2-aminobenzoate, 2-amino-5-chlorophenyl)(phenyl)methanone, and 2-mercapto benzoic acid in acetic acid either a catalyst or solvent at 100 $$^{\circ }$$ ∘ C.
Various 2-[5-(aryl)-1,2,4-oxadiazol-3-yl]quinazolin- $$4(3H)$$ 4 ( 3 H ) -ones have been synthesized from the reaction of diaminoglyoxime-based nitrones with methyl 2-aminobenzoate or 2-aminobenzamide in the presence of acetic acid at $$100\,{^\circ }\mathrm{C}$$ 100 ∘ C . The reaction was extended as a one-pot three-component approach starting from(More)
Improvements in the two-step synthesis of 1,1,1,3,3,3-hexafluoro-2- (fluoromehoxy)propane (Sevoflurane) that result in the product cost reduction, safety level enhancement and positive environmental impacts are described. This process consists of chloromethylation reaction of 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) followed by a halogen-exchange(More)
Radioiodinated meta-iodobenzylguanidine (MIBG) is one of the important radiopharmaceuticals in Nuclear Medicine. [(123/131)I] MIBG is used for imaging of Adrenal medulla, studying heart sympathetic nerves, treatment of pheochromacytoma and neuroblastoma. For clinical application, radioiodinated MIBG is prepared through isotopic exchange method, which(More)
