A series of homo- and heteroditopic thymine- and/or adenine-terminated molecules incorporating rigid aryl or oligo(phenylene ethynylene) linkers has been efficiently synthesized. The key steps involved in the synthesis are the construction of the N-arylated nucleobases using the Chan-Lam-Evans-modified Ullman coupling and their further elaboration using the Sonogashira coupling. Furthermore, the synthesis
已经有效地合成了一系列掺有刚性芳基或低聚(亚苯基亚乙炔基)连接基的,在异位和异位胸腺嘧啶和/或腺嘌呤封端的分子。合成中涉及的关键步骤是使用Chan-Lam-Evans修饰的Ullman偶联物构建N-芳基化核苷碱基,并使用Sonogashira偶联物进行进一步加工。此外,据报道合成了刚性的三脚架胸腺嘧啶衍生物。
