99395-88-7, A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.3663-80-7. An updated downstream synthesis route of 3663-80-7 as follows.
Example 21 (S,E)-3-(pent-2-enoyl)-4-phenyl oxazolidin-2-one The 4S-phenyl-2-oxazolidinone (5.6 g, 34.4 mmol) was placed in a three-necked flask, after it was purged with nitrogen, tetrahydrofuran was added and it was cooled to -78 C., then n-butyl lithium (1.6M, 22 ml, 35.4 mmol) was added dropwise, and the reaction was carried out for 30 minutes. After that, a solution of 2-pentenoyl chloride (4.2 g, 35.5 mmol) in tetrahydrofuran was added dropwise, and the reaction was continued for 30 minutes, then it was slowly raised to 0 C., the reaction was continued for 2 hours and quenched with saturated ammonium chloride solution. The reaction solution was then concentrated to remove tetrahydrofuran and extracted with ethyl acetate 3 times, then the organic phases were combined, washed with saturated brine, dried over anhydrous sodium sulfate, concentrated, and recrystallized with petroleum ether and ethyl acetate to give a white solid 8 g, yield: 95%. 1HNMR (300 MHz, CDCl3): delta 7.3-7.4 (5H, m), 7.1-7.2 (1H, m), 6.9-7.1 (1H, m), 5.5 (1H, dd, J=4.2, 19.0), 4.8 (1H, t, J=9.6, 18.7), 4.2 (1H, dd, J=3.7, 18.9), 2.2 (2H, m), 1.0 (3H, t, J=7.4, 14.9). ESI-MS: 246.4 (M+H)., 99395-88-7
