103260-44-2, Ethyl 2-(tetrahydro-2H-pyran-4-yl)acetate is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of lithium diisopropylamide (1.8 M in THF/heptane/ethylbenzne, 3.6 mL, 6.4 mmol) in 10 mL of THF at -78 0C was added trimethylsilyl chloride (1.4 mL, 11 mmol) dropwise via syringe pump. The product of Example 143B (1.0 g, 5.8 mmol) in 5 mL of THF was then added to the mixture dropwise via syringe pump. The mixture was stirred at -78 0C for 2 hours then N-bromosuccinimide (NuBS, 1.1 g, 6.0 mmol) in 10 mL of THF was added dropwise via syringe pump. The reaction mixture was allowed to warm slowly to ambient temperature and was stirred for 16 h. The mixture was then concentrated under reduced pressure and the residue was dissolved in 20 mL of EtOAc, washed 1 X 5 mL of H2O. The aqueous layer was extracted 3 X 5 mL of EtOAc and the combined organic extracts were dried over anhydrous Na2SO4, filtered, concentrated under reduced pressure and purified via column chromatography (SiO2, 70% hexanes in EtOAc) to provide the title compound (0.70 g, 2.8 mmol, 48% yield). MS (DCIZNH3) m/z 268 (M+NH4)+., 103260-44-2
As the paragraph descriping shows that 103260-44-2 is playing an increasingly important role.
