With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.764-48-7, name is Ethylene Glycol Vinyl Ether, molecular formula is C4H8O2, molecular weight is 88.11, as common compound, the synthetic route is as follows.Safety of Ethylene Glycol Vinyl Ether
General procedure: A dry and argon-flushed 10 mL Schlenk tube, equipped with a stirring bar and septum, wascharged with 2-(vinyloxy)ethanol (5, 132 mg, 1.50 mmol, 1.50 equiv) in Et2O (1.5 mL). Then,iPrMgBr (1.55 mmol, 1.55 equiv) was added dropwise at 25 C. After 5 min of stirring,Sc(OTf)3 (49.2 mg, 0.10 mmol, 0.10 equiv) and aldehyde 6 (1.00 mmol, 1.00 equiv) weresuccessively added and the reaction mixture was stirred at 40 C for the given time. After afull conversion was detected by GC-analysis, sat. aq. NH4Cl (15 mL) was added and theaqueous layer was extracted with EtOAc (3 x 15 mL). The combined organic layers weredried over Na2SO4, filtered and solvent was removed under reduced pressure. Purification viacolumn chromatography (SiO2) afforded expected products 4.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,764-48-7, Ethylene Glycol Vinyl Ether, and friends who are interested can also refer to it.
