A series of substituted 2-aryl imidazo[1,2-a]pyridines has been prepared in which a variety of substituents are introduced on the 4′-position of the phenyl ring and on the 3, 5, 6 or 7 position of the heterocyclic ring. Most examples have acetamido, bromo, cyano, or formyl substituents at the 4′-position. Analogous imidazo-[2,1-b]fhiazoles and imidazo[1,2-a]pyrimidines have also been prepared. Another
一系列取代的2-芳基咪唑并[1,2-α]吡啶已被制备,其中多种取代基被引入在苯环的4'位和在3,5的,6或7位杂环。大多数实例在4'-位具有乙酰氨基,溴,氰基或甲酰基取代基。还已经制备了类似的咪唑并[ 2,1- b ]噻唑和咪唑并[1,2- a ]嘧啶。制备了由咪唑的4'-甲酰基苯氧基甲基衍生物,吡啶,噻唑,苯并咪唑和环取代的咪唑并[1,2- a ]吡啶的三个位置异构体组成的另一系列化合物。还制备了咪唑和咪唑并[1,2- a ]吡啶的2-(4'-甲酰基苯基乙烯基)衍生物。
