A facile and efficient protocol for the synthesis of 2′‐functionalized 1,1′‐binaphthyl‐2‐ols has been developed. The C,O‐dilithio reagent (2) generated by the reductive ring‐opening of binaphthofuran (1) with lithium was treated with the corresponding electrophiles to give 2′‐functionalized 1,1′‐binaphthyl‐2‐ols including the halides (3), amine (4), acid (5), aldehyde (6), carbonate (7) or phosphonate
已经开发了一种简便有效的合成2'功能化的1,1'-联萘-2-醇的方案。将二萘并呋喃(1)与锂还原开环生成的C,O-二硫代试剂(2)用相应的亲电试剂处理,得到2'-官能化的1,1'-联萘-2-醇,包括卤化物(3),胺(4),酸(5),醛(6),碳酸盐(7)或膦酸酯(8),分别以中等至良好的产率。
