A simple procedure for the synthesis of 8-fluoro-3,4-dihydroisoquinoline is described below, based on a directed ortho-lithiation reaction. This key intermediate was then applied in various transformations. Fluorine⁻amine exchange afforded the corresponding 8-amino-3,4-dihydroisoquinolines, suitable starting compounds for the synthesis of 1-substituted 8-amino-tetrahydroisoquinolines. On the other
基于定向邻位锂化反应,以下描述了用于合成8-氟-3,4-二氢异喹啉的简单方法。然后将该关键中间体应用于各种转化中。氟⁻胺交换得到相应的8-氨基-3,4-二氢异喹啉,是合成1-取代的8-氨基-四氢异喹啉的合适起始化合物。另一方面,8-氟-3,4-二氢异喹啉的还原和烷基化反应导致了新的1,2,3,4-四氢异喹啉衍生物,可以用作合成潜在的中枢神经系统候选药物的基础。
