A novel four-component reaction of alkoxyallenes with imines, iodine, and nitriles provided highly substituted imidazole derivatives in high overall yields. The simple three step protocol, exemplified by the reaction of methoxyallene ( 1) with imine 2, acetonitrile, and iodine leading to iodoethenyl imidazole 6 is presented with full experimental detail. Imidazole 6 could be further functionalized
烷氧基丙二烯与亚胺、碘和腈的新型四组分反应以高总产率提供了高度取代的咪唑衍生物。简单的三步方案,以甲氧基丙二烯 (1) 与亚胺 2、乙腈和碘反应生成碘乙烯咪唑 6 为例,并提供了完整的实验细节。咪唑 6 可以通过钯催化偶联进一步功能化,但提供了进入多样性导向合成的途径。
