An efficient synthetic route to construct particular papilionaceous molecules containing oligobenzofurans is described. The key steps involved composing the backbone of the molecules by the Sonogashira cross-coupling reaction, followed by closing the benzofuran ring under alkaline conditions, and further aromatic cyclization of a multi-benzofuranyl precursor using ferric chloride as the oxidative reagent. Basic optical studies (UV-Vis, fluorescence, and fluorescence quantum yield) have been carried out on the synthesized molecules.
本文介绍了构建含有低聚苯并呋喃的特殊木犀草属植物分子的高效合成路线。关键步骤包括通过 Sonogashira 交叉偶联反应合成分子的骨架,然后在碱性条件下关闭苯并呋喃环,并使用三氯化铁作为氧化试剂进一步对多苯并呋喃前体进行芳香环化。对合成的分子进行了基本的光学研究(紫外可见光、荧光和荧光量子产率)。
