9/16/21 News New learning discoveries about 1883-32-5

Statistics shows that 1883-32-5 is playing an increasingly important role. we look forward to future research findings about 2,2-Diphenylethanol.

Electric Literature of 1883-32-5, 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.1883-32-5, name is 2,2-Diphenylethanol, molecular formula is C14H14O, molecular weight is 198.26, as common compound, the synthetic route is as follows.

General procedure: A mixture of 3,4,6-tri-O-acetyl-D-glucal 1 (50.0 mg, 0.184 mmol) and alcohol (0.193 mmol) was dissolved in dry-CH2Cl2 : dry-toluene (125 : 200 muL) under gas-nitrogen. The solution was cooled to 0 C, then 0.5 M IBr in CH2Cl2 (20 mol%, 75 L) was added slowly. The stirring was continued at 0-20 C for 1-10 h. After TLC showed the completed conversion, the reaction mixture was quenched carefully with cooled aq.Na2S2O3 (20 mL) and washed with satd aq. NaHCO3 (20 mL), and extracted with EtOAc (3×20 mL). The combined organic layer was washed with brine (20 mL), dried over anhydrous Na2SO4, and then concentrated under reduced pressure. The residues were purified by silica gel column chromatography (EtOAc/n-hexane) to give the 2,3-unsaturated-O-glycoside products 2a-2t in good to high yields (71-99%). In most cases, a mixture of alpha and beta-anomers of glycoside 2 was obtained. The ratio of the isomers was determined by comparison of the integration values of the peaks in 1H NMR analysis. The alpha-configuration was characterized from the position of anomeric proton which appears in an up fieldposition compared to -anomer in most cases. The beta-isomers was not separated but characterized compared with the literature data of the mixture. Spectral data of pure alpha-isomers are as followed.

Statistics shows that 1883-32-5 is playing an increasingly important role. we look forward to future research findings about 2,2-Diphenylethanol.

Extracurricular laboratory: Synthetic route of 1883-32-5

With the rapid development of chemical substances, we look forward to future research findings about 1883-32-5.

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. 1883-32-5, name is 2,2-Diphenylethanol, molecular formula is C14H14O, 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. Application In Synthesis of 2,2-Diphenylethanol

General procedure: Substrates, 1 and 2, were synthesized by the same method of 2-adamantyl chloroformate. The triphosgene treated in toluene at 0-4 C (ice bath) for 20 min. The mixture of 2-phenylethanol or 2,2-diphenylethanol with pyridine was prepared in toluene at room temperature. Then the latter mixture was added to the former solution slowly. After the stirring for 1 h, the organic mixture was washed with water and dried by magnesium sulfate. The solvent was removed by the evaporation, the colorless oil (1) or white solid (2) was obtained as a crude product. The substrate 1 was purified from vacuum distillation (120 C and 18 torr) and the substrate 2 was recrystallized by using ligroin. Solvents were purified as described previously.

With the rapid development of chemical substances, we look forward to future research findings about 1883-32-5.
