22348-32-9, (R)-Diphenyl(pyrrolidin-2-yl)methanol is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step 3A. Preparation of TMS-prolinolTo a mixture of prolinol (10.0 g, 39.5 mmol) and imidazole (4.57 g, 67.1 mmol) in THF (100 mL) was added chlorotrimethylsilane (5.57 g, 51.3 mmol) over 15 min while maintaining the batch temperature below 30 0C. The resulting slurry was aged at 50 0C for 3-5 h. The reaction mixture was cooled to ambient tempearture and quenched by addition of MTBE (50 mL) and 15% aq NaCl (100 mL). The organic layer was washed with 15% aq NaCl (50 mL). The solution was azeotropically dried at the constant volume by feeding THF.HPLC MethodColumn: Ascentis Express Cl 8 (100×4.6mm, 2.7um)Column temperature: 45 0CFlow rate: 1.5 ml/minDetection: UV at 210nmGradient:Time(min) 0.1% H^PO4 (0A) MeCN (0A)0 95 51 95 512 10 90Retention times (minutes): prolinol (4.8 min); TMS prolinol (7.3 min), 22348-32-9
The synthetic route of 22348-32-9 has been constantly updated, and we look forward to future research findings.
