A facile, one-pot stereoselective synthesis of novel trans-4,5-dihydroxy-2-aryl-1,3-bis(heteroaryl)imidazolidines is achieved by a cyclocondensation reaction of 2 equiv of heteroarylamines with benzaldehyde derivatives, in the presence of guanidinium chloride as a polyfunctional organocatalyst, with aqueous glyoxal to afford the title products. This general protocol provides a wide range of new polyfunctionalized
一种新的反式-4,5-二羟基-2-芳基-1,3-双(杂芳基)咪唑烷类化合物的简便,一锅立体选择性合成是通过在芳烃存在下,将2个当量的杂芳基胺与苯甲醛衍生物进行环缩合反应而实现的。氯化胍作为多官能有机催化剂,与乙二醛水溶液可提供标题产物。该通用方案以良好至高收率提供了多种新型的多官能化咪唑烷。
