What are the synthesis methods of (1S) - (+) -3-Endo-Bromocamphor-10-Sulfonic Acid?
The synthesis method of (1S ) - ( + ) - 3-bromocamphor-10-sulfonic acid is described in ancient books and is described in detail below.
First, camphor is taken as the base, which is especially important in organic synthesis because of its special bridge ring structure. The halogenation reaction is carried out under suitable reaction conditions with appropriate halogenating reagents, such as bromine. Among these, the choice of reaction temperature and solvent is the key. If the temperature is too high, it is easy to cause side reactions to cluster; if the temperature is too low, the reaction will be delayed. Choosing a non-polar or weakly polar solvent, such as dichloromethane, can make the reaction proceed smoothly, and is conducive to the dissolution of bromine and the maintenance of reaction activity. In this process, bromine atoms will be selectively added to specific positions of camphor to generate 3-bromocamphor intermediates.
Then, for this intermediate, a sulfonic acid group is introduced. Fuming sulfuric acid or chlorosulfonic acid is often used as a sulfonation reagent. During the reaction, control the amount of reagent and the reaction time. If the dosage is too much or the time is too long, it is easy to cause excessive sulfonation; if the dosage is too little or the time is insufficient, the sulfonation will be incomplete. Under a certain temperature and stirring conditions, the sulfonic acid group will replace the hydrogen atom at a specific position to form (1S ) - ( + ) - 3-inner-bromocamphor-10-sulfonic acid.
After the reaction is completed, it needs to be separated and puri Can take advantage of its physical properties, such as different solubility, recrystallization operation. Select the appropriate solvent, heat the dissolved product, while hot filtration, cooling crystallization, can obtain a pure product. Or column chromatography, select the appropriate stationary phase and eluent, the product and impurities are separated for the purpose of purification.
