Synthetic Route of 10601-80-6,Some common heterocyclic compound, 10601-80-6, name is Ethyl 3,3-diethoxypropionate, molecular formula is C9H18O4, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: 2-aminopyridine 1a (47 mg, 0.5 mmol), ethyl 3,3-diethoxypropanoate 2 (285 mg, 1.5 mmol) and p-TsOH (8.6 mg, 10 mol %) were stirred in 2 mL of toluene for 6 h at 80 C. After completion of the reaction (monitored by TLC), the water (10 mL) was added. The aqueous solution was extracted with ethyl acetate (3×8 mL) and the combined extract was dried with anhydrous MgSO4. The solvent was removed and the crude product was separated by column chromatography (eluted with petroleum ether/ethyl acetate = 2:1) to give a pure sample of 3a (Yellow crystal, 100 mg, 82%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Ethyl 3,3-diethoxypropionate, its application will become more common.
