A convergent access to substituted 2-iminoimidazolidines from aromatic amines and -propargyl -methylthiourea is developed via Ag(I)-mediated cascade guanylation-cyclization reactions. This method features high regioselectivity, excellent efficiency, and mild reaction conditions. Subsequent deprotection of the Boc (-butyloxycarbonyl) group under acidic conditions provides expedient access to aryl 2-aminoimidazole derivatives in a convenient manner.
一种从芳基胺和 -炔丙基 -甲基硫脲出发的取代 2-亚氨基咪唑烷的收敛性合成方法通过 Ag(I)-介导的级联鸟苷化-环化反应得到。该方法具有高区域选择性、高效率和温和的反应条件。随后在酸性条件下脱除 Boc（-叔丁氧羰基）保护基，以方便的方式提供了方便的芳基 2-氨基咪唑衍生物。
