Synthetic Route of 103-50-4, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 103-50-4 as follows.
General procedure: To a test tube charged with CuCl (2.0 mg, 0.02 mmol) andisochroman (1a; 251 muL, 2.0 mmol) in t-BuOH (20 mL) wasadded TBHP (5.0-6.0 M in decane, 10.9 muL, 0.6 mmol) and themixture was stirred and heated at 50 C for 12 h under open air.After cooling to room temperature, the reaction was quenchedwith 25% aqueous ammonia solution and water then themixture was extracted with EtOAc. The separated organic layerwas dried over Na2SO4 and products were concentrated after filtration.The residue was purified by silica gel column chromatography(EtOAc/hexane, 1:10) to give isochromanone (2a) as acolorless oil in 83% yield.
According to the analysis of related databases, 103-50-4, the application of this compound in the production field has become more and more popular.
