To prepare (1R, 4R) -7,7-dimethyl-2-oxobicyclic [2.2.1] heptyl-1-yl acetic anhydride, the following ancient methods can be used.
First take a suitable starting material, often with dicyclic [2.2.1] heptyl-5-ene-2,3-dicarboxylic anhydride as the beginning. This anhydride is converted by a specific reaction, such as an appropriate reducing agent, under mild conditions, the anhydride part is moderately reduced, and an intermediate containing a specific hydroxyl group can be obtained. When operating, pay attention to the reaction temperature and the amount of reducing agent, and do not over-reduce.
Then, methylate the intermediate. Select a suitable methylating agent, such as iodomethane, and react in an alkaline environment. The strength and dosage of the base need to be precisely controlled to ensure that the methylation check point is accurate and the required 7,7-dimethyl intermediate is generated.
Then, the resulting product is oxidized to obtain a 2-oxo product. Selecting a suitable oxidant, such as Dyce-Martin oxidant, and reacting in a suitable organic solvent can effectively oxidize the target site to a carbonyl group to obtain (1R, 4R) -7,7-dimethyl-2-oxobicyclo [2.2.1] heptyl-1-carboxylic acid.
Finally, the carboxylic acid is converted to an acid anhydride. Treated with a dehydrating agent such as acetic anhydride, at an appropriate temperature and reaction time, the carboxylic acid fully reacts with the dehydrating agent, and after dehydration condensation, the final product is (1R, 4R) -7,7-dimethyl-2-oxobicyclic [2.2.1] heptyl-1-yl acetic anhydride. After each step of the reaction, it needs to be finely separated and purified to maintain the purity of the product. Follow this step to obtain the target product.
