1-t-Butyldimethylsiloxy-3-arylisobenzofurans, a new type of isobenzofurans, were generated from 3-arylphthalides by sequential treatment with LDA and TBDMSCl. The isobenzofurans, thus formed, were intercepted in situ by dimethyl fumarate to give stable Diels–Alder adducts in good yields. These adducts were converted into 4-aryl-1-naphthols by acid treatment. This new route for the preparation of naphthols was
1-t-丁基二甲基甲硅烷氧基-3-芳基异苯并呋喃是一种新型的异苯并呋喃,由 3-芳基苯酞通过 LDA 和 TBDMSCl 连续处理生成。由此形成的异苯并呋喃被富马酸二甲酯原位拦截,以良好的产率得到稳定的狄尔斯-阿尔德加合物。这些加合物通过酸处理转化为 4-芳基-1-萘酚。这种制备萘酚的新路线被应用于合成天然芳基萘木酚素、木酚素。
