Abstract The alkylation of ethyl 2-aryl-1-hydroxy-4-methyl-1H-imidazole-5-carboxylates with substituted benzyl halides resulted in the selective formation of O-alkoxy derivatives. N-Alkylation products (1-alkylimidazole 3-oxides) were obtained by the condensation reaction from acyclic starting compounds. In the presence of the 2-hydroxyphenyl substituent in the 2-position of the imidazole ring, selective
摘要 2-芳基-1-羟基-4-甲基-1H-咪唑-5-甲酸乙酯与取代的苄基卤的烷基化导致选择性形成O-烷氧基衍生物。 N-烷基化产物(1-烷基咪唑3-氧化物)是通过无环起始化合物的缩合反应获得的。当咪唑环2-位上的2-羟基苯基取代基存在时,涉及咪唑氮上的羟基取代基的选择性单烷基化发生。
