of the latter with potassium ferricyanide in an alkaline medium according to the Jacobson method yielded 2-(thien-2-yl)naphtho[1,2-d]thiazole. The latter was introduced into the electrophilic substitution reactions: nitration, bromination, formylation, and acylation. The reactions occur exclusively at the position 5 of the thiophene ring.
摘要 1-氨基萘与噻吩-2-羰基氯在2-丙醇中的缩合反应,得到N-(1-萘基)噻吩-2-羧酰胺,在无水吡啶中用过量的P 2 S 5处理得到相应的硫代酰胺。根据Jacobson方法,在碱性介质中用铁氰化钾氧化后者,得到2-(噻吩-2-基)萘并[1,2- d ]噻唑。后者被引入亲电取代反应中:硝化,溴化,甲酰化和酰化。该反应仅在噻吩环的5位发生。
