With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.118399-28-3,(R)-Benzyl (5-oxotetrahydrofuran-3-yl)carbamate,as a common compound, the synthetic route is as follows.
12. Synthesis of intermediate 5c (0389) Exact Mass: 363.22 (0390) (0391) 4 5c (0392) [00135] To the solution of intermediate 4 (6.5 g, 27.7 mmol) in THF (100 mL) was added intermediate c (3.6 g, 27.7 mmol), and the solution was stirred at room temperature overnight. After completion of the reaction, the solvent was removed in vacuo, the residue was purified by chromatography column (PE EA = 3/1) to afford intermediate 5c (7.2 g, 72%) as yellow oil. 3, 118399-28-3
The synthetic route of 118399-28-3 has been constantly updated, and we look forward to future research findings.
