An unprecedented PTSA-promoted furan annulation and aromatization in one pot has been developed. This process offers a simple and efficient synthetic route for the construction of various highly substituted benzo[b]furan derivatives, which are widely used not only in drug active molecules but also organic semiconductor and organic light-emitting devices. The preliminary mechanism study indicated this
在一个锅中开发了前所未有的PTSA促进的呋喃环化和芳构化。该方法为构建各种高度取代的苯并[ b ]呋喃衍生物提供了简单而有效的合成途径,这些苯并[ b ]呋喃衍生物不仅广泛用于药物活性分子中,而且还广泛用于有机半导体和有机发光器件中。初步的机理研究表明,该转化通过呋喃环化和芳构化依次进行。
