7-iminodimethylene)anthraceneand bis-(2,3:6,7-iminodimethylene)-9,10-dicarboxyethenoanthracene,by means of Diels-Alder reaction between 1,2,4,5-tetra(dibromo?methyl)benzeneand maleimides followed by imide reduction, is described. Furthermore,these two cyclic secondary diamines undergo acylation with N-protectedamino acids, thus providing functionalized, amphiphilic, and chiralbuilding blocks for incorporation
Diels-Alder反应合成双(2,3:6,7-亚氨基二亚甲基)蒽和双-(2,3:6,7-亚氨基二甲基)-9,10-二羧基乙烯蒽两种刚性多环仲二胺描述了 1,2,4,5-四(二溴甲基)苯和马来酰亚胺之间的反应,然后进行酰亚胺还原。此外,这两个环状仲二胺与 N 保护的氨基酸发生酰化,从而提供功能化、两亲性和手性结构单元,用于掺入超分子系统。
