With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.90319-52-1,(R)-4-Phenyloxazolidin-2-one,as a common compound, the synthetic route is as follows.
Preparation of (i?)-3-cinnamoyl-4-phenyloxazolidin-2-one: A THF (50 mL) solution of (i?)-4-phenyloxazolidin-2-one (5.90 g, 36.2 mmol) was cooled to -78 ¡ãC and treated with lithium bis(trimethylsilyl)amide (36.9 mL, 36.9 mmol, 1.0 M in THF) dropwise over 15 minutes. After 15-minute stirring at -78 ¡ãC, a THF (10 mL) solution of cinnamoyl chloride (6.33 g, 38.0 mmol) was then introduced. The mixture was stirred for 1 hour at -78 ¡ãC and 2 hours at ambient temperature before it was quenched with saturated NaHCC>3 (50 mL) and stirred for 1 hour. The mixture was diluted with EtOAc (200 mL), washed with water and brine, dried over MgS04, filtered and concentrated to give the product as a pale yellow solid (10.6 g, 99.9percent yield). MS (apci) m/z = 293.9 (M+H)., 90319-52-1
The synthetic route of 90319-52-1 has been constantly updated, and we look forward to future research findings.
