SDS of cas: 23062-51-3

Methyl 4- bromobicyclo [2.2.2]octane-l-carboxylate (17.0 g, 69.0 mol) was refluxed in aqueous sodium hydroxide solution (1500 mL, 1 %) for 24 h. After cooling, the reaction solution was acidified with hydrochloric acid (6 N, 100 mL) and extracted with diethyl ether (6 x 500 mL). The combined ether layers were dried over magnesium sulfate and concentrated to afford the title compound (10.4 g, 61.1 mmol, 89 % yield), which was used in the next step without further purification. MS (ESI) m/z 169.2 [M-H]~.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 23062-51-3, its application will become more common.

Electric Literature of 23062-51-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 23062-51-3, name is Methyl 4-bromobicyclo[2.2.2]octane-1-carboxylate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.

A solution of XVIII-2 (6 g, 24.2 mmol) in anhydrous benzene (60.15 g) was added dropwise to an ice-water cooled suspension of AlCl3 (5.95 g, 45.1 mmol) in benzene (60.15 g) under nitrogen. The resulting reaction mixture was allowed to stirred in the ice bath for 30 min and then at rt overnight. The mixture was heated to 60 C. for 4 h and then allowed to cool to rt and poured into ice and concentrated HCl. The mixture was extracted with EtOAc, washed with brine, separated, and dried over Na2SO4 to leave an orange-brown solid, which was purified by column chromatography (PE:EA=10:1) to afford XVIII-3 (2.3 g, yield: 38.6%).

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Methyl 4-bromobicyclo[2.2.2]octane-1-carboxylate, other downstream synthetic routes, hurry up and to see.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 23062-51-3, name is Methyl 4-bromobicyclo[2.2.2]octane-1-carboxylate, A new synthetic method of this compound is introduced below., Recommanded Product: Methyl 4-bromobicyclo[2.2.2]octane-1-carboxylate

To the title compound from the Preparative Example 55, Step A (677 mg) was added 10% aqueous NaOH (65 niL). The mixture was stirred at 100C (temperature of the oil bath) for 42 h, concentrated to 15 mL and diluted with IN aqueous HCl (3O mL). The resulting mixture was acidified to pH 1 with 12N aqueous HCl and extracted with EtOAc (5 x 70 mL). The combined organic phases were dried (MgSO4), filtered and concentrated to afford the title compound (540 mg, 89%). [MH]+ = 171

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
