To prepare [ (1S) -internal type] - (+) -3-bromo-7,7-dimethyl-2-oxo-bicyclic [2.2.1] heptane-1-methanesulfonic acid, monohydrate, the method is as follows:
First take dicyclo [2.2.1] heptyl-5-ene-2-one as the starting material, which is the basis of the reaction. In an appropriate reaction vessel, add an appropriate amount of brominating reagent, and control the reaction temperature, time and ratio of reactants. The brominating reagent reacts with dicyclo [2.2.1] heptyl-5-ene-2-one, and the bromine atom is cleverly added to a specific position to form a bromine-containing intermediate. This process needs to be carefully controlled. If the temperature is too high, side reactions may occur; if the time is too short, the reaction may be incomplete.
Then, for the obtained bromine-containing intermediate, a methanesulfonate group is introduced. Select a suitable methanesulfonation reagent, and under a specific reaction environment, such as a suitable solvent and pH, the methanesulfonate group is successfully connected to the intermediate to form [ (1S) -internal type] - (+) -3-bromo-7,7-dimethyl-2-oxo-dicyclo [2.2.1] heptane-1-methanesulfonic acid.
Finally, it is combined with an appropriate amount of water to form a monohydrate. In this step, attention should be paid to the water content of the reaction system. Too much or too little is not conducive to the formation of monohydrate. After multi-step reaction, the impurities can be removed by separation and purification methods such as recrystallization and column chromatography to obtain pure [ (1S) -internal type] - (+) -3-bromo-7,7-dimethyl-2-oxo-dicyclo [2.2.1] heptane-1-methanesulfonic acid, monohydrate. The whole preparation process is interlocking, and it is necessary to accurately grasp the reaction conditions in order to achieve the expected results.

(I look at this [ (1S) -internal type] - (+) -3-bromo-7,7-dimethyl-2-oxo-bicyclic [2.2.1] heptane-1-methanesulfonic acid monohydrate, and many matters should be paid attention to when it is used.)
First of all, this product has special properties and must strictly abide by the experimental procedures when operating. Because of its unique chemical structure, reactive activity or different from normal products. Make sure that the experimenter is familiar with its characteristics to prevent unexpected reaction bursts.
Furthermore, storage should not be taken lightly. This product may be sensitive to environmental factors, such as changes in temperature and humidity. When choosing a suitable place and storing it properly, in order to ensure the stability of its chemical properties, do not deteriorate and cause deviation of experimental results.
In addition, during use, protection is indispensable. This material may be corrosive and irritating to a certain extent, and the experimenter should wear complete protective equipment, such as gloves, goggles, etc., to avoid its damage to the body.
