A new and one-pot synthesis of benzofuran fused N-heterocycles has been accomplished via AlCl3-mediated C–C followed by C–O bond formation between 2,3-dichloropyrazine or its derivatives and phenols. The methodology provided novel compounds as potential inhibitors of PDE4B. The single crystal X-ray data of a synthesized benzofuran derivative are presented. Scope of the methodology, in vitro pharmacological
通过AlCl 3介导的C–C,然后在2,3-二氯吡嗪或其衍生物与酚之间形成C–O键,已经完成了一种新的一锅法合成苯并呋喃稠合的N-杂环。该方法提供了新型化合物作为PDE4B的潜在抑制剂。给出了合成的苯并呋喃衍生物的单晶X射线数据。描述了方法的范围,一些合成化合物的体外药理数据以及对活性化合物的对接研究。
