We know that the rate of many reactions can be accelerated by catalysts. A catalyst speeds up the rate of a reaction by lowering the activation energy; in addition, the catalyst is regenerated in the process. 108149-63-9, name is (R)-tert-Butyl 4-(hydroxymethyl)-2,2-dimethyloxazolidine-3-carboxylate,below Introduce a new synthetic route., 108149-63-9
Step 2: (S)-tert-Butyl 4-((4-bromo-2-chIoro-6-methylphenoxy)methyl)-2,2- dimethyIoxazolidine-3-carboxylate (23). To a solution of compound 22 (4 g, 18 mmol), intermediate 2 (4.8 g, 21.7 mmol) and triphenylphosphine (7.0 g, 27 mmol) in DCM (80 mL) was added diisopropylazodicarboxylate (5.4 g, 27 mmol). The reaction mixture was stirred at RT for 3 h. Water was added and the product was extracted with DCM. Purification by flash column chromatography gave the desired product 23 (5.8 g, 73%)., 108149-63-9
Other significant industrial processes that involve the use of heterogeneous catalysts include the preparation of sulfuric acid, the preparation of ammonia, the oxidation of ammonia to nitric acid, and the synthesis of methanol. 108149-63-9, if you are interested, you can browse my other articles.
