Cyclo-bisintercalands are macrocyclic systems containing aromatic subunits, which are commonly used as hosts for aromatic molecules and as DNA intercalators. In this article, a step-by-step synthesis of a series of cyclo-bisintercalands containing 3,6-diaminoacridines as aromatic units, and connected by rigid spacers of different lengths, is reported. In addition, we describe herein a more efficient
环-双intercalands是包含芳族亚基的大环系统,通常用作芳族分子的宿主和DNA嵌入剂。在本文中,报告了逐步合成一系列包含3,6-二氨基ac啶作为芳香族单元并通过不同长度的刚性间隔基连接的环双双间隔环的方法。另外,我们在本文中描述了一种更有效的合成替代方案,涉及单步模板指导的过程。新路线允许以可接受的收率容易地合成地进入这些大环系统。合成的双环双间隔环及其前体在结构上已通过紫外可见和NMR方法进行了表征。
