Abstract

The meta-linked bissquaramides and were synthesized and spectroscopically characterized. Compound , composed of two N,N′-dialkyl-N,N′-diphenylsquaramides sharing a common benzene ring, exhibits CD signals characteristic of right-handed helicity, despite the S-chirality of each unit and its left-handed-helical structure in X-ray crystal analysis. This inversion arises from the interaction of the electric transition moments of the two units.
基于(顺式,顺式)-方酰胺的芳香层状折叠物:手性诱导和绝对结构。
合成了元连接双鲨酰胺8和9,并对其进行了光谱表征。化合物9由两个N,N'-二烷基-N,N'-二苯基方酰胺6组成,共用一个苯环,尽管x射线晶体分析显示每个单元的s手性和左螺旋结构,但其CD信号具有右手螺旋特征。这种反转是由两个单元的电跃迁矩的相互作用引起的。
