Salgado-Zamora, Hector published the artcileA convenient approach to the synthesis of the imidazo[5,1-b]oxazole ring system, Product Details of C4H4BrN3O2, the main research area is imidazole bromomethylnitrophenacyl intramol cyclization potassium butoxide; imidazooxazole preparation; oxazole imidazo preparation.
Reaction of 4(5)-bromo-2-methyl-5(4)-nitroimidazole with phenacyl bromide derivatives ArCOCH2Br (Ar = Ph, 4-ClC6H4, 3-F3CC6H4, etc.) led to 4-bromo-2-methyl-1-phenacyl-5-nitro- and 5-bromo-2-methyl-1-phenacyl-4-nitroimidazoles I (X1 = NO2, X2 = Br; X1 = Br, X2 = NO2). Treatment of the latter isomers with potassium tert-butoxide in dry THF yielded imidazo[5,1-b]oxazoles II.
Heterocycles published new progress about Crystal structure. 18874-52-7 belongs to class imidazoles-derivatives, name is 5-Bromo-2-methyl-4-nitroimidazole, and the molecular formula is C4H4BrN3O2, Product Details of C4H4BrN3O2.
