| titleOfInvention | The preparation method of 3-substituted-phenyl-5-An Jia Ji oxazolidine-2-ketone |
| abstract | The invention discloses a kind of preparation method of 3-substituted-phenyl-5-An Jia Ji oxazolidine-2-ketone: substituted aniline and (R)-polychlorinated dibenzo-furans are obtained by reacting (R)-3-substituted benzene amino-2-hydroxyl-chloropropane, (R)-3-substituted benzene amino-1-dibenzyl amino-2-propyl alcohol is obtained by reacting again with dibenzylamine, cyclization obtains (S)-3-substituted-phenyl-5-dibenzyl An Jia Ji oxazolidine-2-ketone, last hydrogenation debenzylation obtains (S)-3-substituted-phenyl-5-An Jia Ji oxazolidine-2-ketone.The compound that the present invention obtains is the important intermediate of commercial Sheng Chan oxazolidinone antiseptic-germicide.Four-step reaction of the present invention prepares the method for 3-substituted-phenyl-5-An Jia Ji oxazolidine-2-ketone, there is the features such as step is few, simple to operate, raw material is cheap and easy to get, reaction conditions is gentle, not only increase production efficiency, reduce production energy consumption, and also improve safety in production coefficient, decreasing environmental pollution, is the green synthesis method of a kind of environmental friendliness, low-carbon (LC). |
