摘要 以咪唑为起始原料,经二甲胺基磺酰氯保护,在正丁基锂条件下,分别与各种亲电试剂反应得到1-(二甲胺基磺酰基)-2-取代-咪唑,最后在稀盐酸条件下脱保护合成了一系列2-取代咪唑衍生物,其结构经1H NMR、MS和元素分析表征。 A series of 2-substituted imidazoles were synthesized from imidazole which was first protected with N,N-dimethylsulfonyl chloride,and then reacted with different electrophilic reagents under the catalysis of n-butyl lithium,followed by detach of the protection group in dilute hydrochloric acid.The structures were characterized with 1H NMR,MS and elemental analysis.
