90319-52-1, (R)-4-Phenyloxazolidin-2-one is a oxazolidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 35 (R,E)-3-(3- (3-benzyloxy) phenyl) acryloyl)-4-phenyl oxazolidin-2-one The m-benzyloxy cinnamic acid (90g, 354mmol) was dissolved in dichloromethane (25ml), oxalyl chloride (45ml) was added therein and it was reacted at room temperature for 5 hours, then the reaction solution was concentrated to remove the solvent and oxalyl chloride for further use; 4(R)-phenyl-2-oxazolidinone (57g, 350mmol) was dissolved in dichloromethane, the mixture was cooled to 0¡ãC, and 4-dimethylamino pyridine (4.3g, 35mmol) and triethylamine (76 mL, 525mmol) was added, then the solution of m-benzyloxy cinnamic acid in dichloromethane was added. After that, the reaction was continued for 8 hours and quenched with saturated ammonium chloride solution, then the reaction solution was separated, the dichloromethane layer was washed with water and saturated brine, dried over anhydrous sodium sulfate, concentrated and recrystallized with petroleum ether and ethyl acetate to give a white solid 144g, yield: 95percent. The HNMR spectrum data is the same as that in, 90319-52-1
The synthetic route of 90319-52-1 has been constantly updated, and we look forward to future research findings.
