Nine novel (+)‐camphor‐derived thioureas have been prepared. 3‐((Dimethylamino)methylene)camphor (2) served as the common precursor for the preparation of both, 2‐thiourea 15, 16, 17, 18, 19, 20 and 3‐thiourea functionalized camphor derivatives 6, 7/7', respectively. Starting from 2, the latter were prepared in two or three steps whereas the former in five steps, respectively. Configuration of all
制备了九种新颖的(+)-樟脑胶衍生的硫脲。3 - ((二甲基氨基)亚甲基)樟脑(2)作为两个的制备中的共同的前体,2-硫脲15,16,17,18,19,20和3 -硫脲官能樟脑衍生物6,7 / 7', 分别。从2开始,后者分两步或三步准备,而前者分五步准备。所有新化合物的构型都是使用NMR技术和/或单晶X射线晶体学方法精心确定的。手性,2012年。©2012 Wiley Periodicals,Inc.。
