EN Dihydrooxazole ring opening reactions in bicyclic nitroimidazodihydrooxazoles with simultaneous Williamson ethe real groups formation are described. It was found that only mutual action of K2CO3, phenol and alcohol can cause such reaction. Its mechanism consists of three steps. In a result, a series[...]

EN Several 1-(chloro, fluoro, dichloro or difluorophenyl)-4-nitroimidazoles and their 2-methyl derivatives have been prepared by the reaction of respectively substituted anilines with 1,4-dinitroimidazoles via a degenerated imidazole ring transformation. The structures of the obtained products were cha[...]

EN Reaction of 4(5)-bromo-2-methyl-5(4)-nitroimidazole with phenacyl bromide derivatives gave two isomers: 4-bromo-5-niroimidazoles (4a-e) and 5-bromo-4-nitroimidazoles (5a-e). Compounds 5a-e were treated with cyclic secondary amines to afford expected 5-amino-4-nitroimidazole derivatives 6a-c - 10a-b.
