titleOfInvention | A kind of preparation method of trans-(N-4-Boc-aminocyclohexane)acetic acid |
abstract | The invention discloses a preparation method of trans-(N-4-Boc-aminocyclohexane)acetic acid, and belongs to the technical field of organic synthesis. The specific steps are as follows: the carboxyl group of trans-4-Boc-aminocyclohexanecarboxylic acid is reduced to obtain trans-(N-Boc-4-aminocyclohexyl)methanol, followed by carbon tetrabromide and triphenylphosphine in The reaction is carried out in dichloromethane solution to obtain trans-(N-4-Boc-aminocyclohexane)ethyl bromide, and then the Grignard reagent is exchanged and carbon dioxide is introduced to obtain trans-(N-4-Boc-aminocyclohexane)acetic acid . The raw materials used in the invention are cheap and easy to obtain, have high yield, avoid large-scale toxic cyanide, reduce steps, are suitable for large-scale production, avoid the use of p-toluenesulfonate with genotoxicity, and can be widely used in the field of pharmacy . |
