| titleOfInvention | The method of furan ammonium salt cis-trans-isomer conversion |
| abstract | The invention belongs to technical field of medical intermediate preparation, a kind of method for being specifically related to furan ammonium salt cis-trans-isomer conversion.Furan ammonium salt transisomer (E)-SMIA is initially dissolved in organic solvent, it carries out isomerization reaction in organic solvent with catalyst again, i.e., (E)-SMIA is transformed into isomers of taking advantage of a situation (Z)-SMIA of furan ammonium salt.In present invention process implementation process catalyst can iterative cycles utilize, experimental verification catalyst circulation use 101 times after, conversion rate of products has no reduction, and catalyst structure does not observe variation sign；Operating process is simple, does not add any additive in conversion process, does not generate any other three wastes, and production technology is environmentally protective. |
