摘 要:以对甲苯磺酸吡啶盐作催化剂,2,3-二氢呋喃和2,3-二氢吡喃为起始原料,与醇通过加成反应制备得到2-甲氧基四氢呋喃和2-(2-溴代)乙氧基四氢吡喃,并通过Gabriel伯胺合成法得到O-(四氢-2H-吡喃-基)羟胺。对甲苯磺酸吡啶盐催化的收率均在85%以上,其结构经1H NMR和MS确证。此法广泛应用于羟基和氨基的保护,具有操作简便、条件温和、原料成本低等优点。

Abstract:2-Methoxytetrahydrofuran and 2-(2-bromo)ethoxytetrahydropyran were obtained using 2,3-dihydrofuran or 2,3-dihydropyran as the starting material while p-toluenesulfonic acid pyridine salt as the catalyst. Meanwhile, O-(tetrahydro-2H-pyran-yl) hydroxylamine was prepared via Gabriel reaction. The structures were proved by 1H NMR and MS spectra, and the yield of target products were more than 85%.This method could be widely used in the protection of hydroxyl and amino groups with the advantages of simple operation, mild conditions, low cost of raw materials.
Key words:p-toluenesulfonic acid pyridine sal; 2,3-dihydrofuran; 2,3-dihydropyran; etherification
