We report herein a new metal free synthetic pathway to generate tetracyclic compounds from 3-aminothieno[3,2-b]pyridine-2-carboxylate. To enlarge the molecular diversity, we studied the Suzuki coupling of 9-chloro-6H-pyrido[1,2-a]pyrido[2',3':4,5]thieno[3,2-d]pyrimidin-6-one and several boronic acids were easily introduced.
我们在此报告了一种新的无金属合成途径,可从3-氨基噻吩并[3,2-b]吡啶-2-羧酸酯生成四环化合物。为了扩大分子多样性,我们研究了9-氯-6H-吡啶并[1,2-a]吡啶并[2',3':4,5]噻吩并[3,2-d]嘧啶-6-的铃木偶联。容易引入一种和几种硼酸。
