| titleOfInvention | A kind of method that novel high cis-selectivity prepares hexamethylene -2,4- diene ketone derivatives |
| abstract | The present invention provides a kind of novel high cis-selectivities to prepare hexamethylene -2, the method of 4- diene ketone derivatives, after high iodine catalyst and trifluoroethanol is added in racemic phenol analog derivative, aromatization reaction is directly carried out under the conditions of -40 ° ~ 25 ° of temperature；Wherein, R 1 For tert-butyl, phenyl, trimethylsilyl or isopropyl；R 2 For tert-butyl, phenyl, trimethylsilyl or isopropyl.The racemic phenol analog derivative structural formula is as follows.The high iodine compound that the present invention uses is cheap, excellent, while meeting the theory of Green Chemistry, participates in reaction it is not necessary that each heavy metal species or noble metal are added, reduces the destruction to environment.The advantages that reaction has easy to operate, is simple and efficient, and yield is high, and side reaction is few, is natural products, pharmaceutical synthesis research and development provide Research foundation. 、 |
