摘 要:以對甲苯磺酸吡啶鹽作催化劑,2,3-二氫呋喃和2,3-二氫吡喃為起始原料,與醇通過(guò)加成反應制備得到2-甲氧基四氫呋喃和2-(2-溴代)乙氧基四氫吡喃,并通過(guò)Gabriel伯胺合成法得到O-(四氫-2H-吡喃-基)羥胺。對甲苯磺酸吡啶鹽催化的收率均在85%以上,其結構經(jīng)1H NMR和MS確證。此法廣泛應用于羥基和氨基的保護,具有操作簡(jiǎn)便、條件溫和、原料成本低等優(yōu)點(diǎn)。 |

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 |
