764-48-7, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 764-48-7, name is Ethylene Glycol Vinyl Ether, molecular formula is C4H8O2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
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.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 764-48-7, Ethylene Glycol Vinyl Ether, other downstream synthetic routes, hurry up and to see.
