| titleOfInvention | The method of synthesis 2-thia two ring [3.1.0]-3-hexene-6-manthanoate |
| abstract | The invention discloses a kind of method of synthesis 2-thia two ring [3.1.0]-3-hexene-6-manthanoate, step is: 0-140 DEG C under agitation drips diazonium acetate or diazoacetic acid ester solution in the mixture of catalyzer and thiophene and solvent, reacts to gas and drains; Filtration of catalyst, steams excessive thiophene and solvent; Finally be isolated to 2-thia two ring [3.1.0]-3-hexene-6-manthanoate.Wherein, described catalyzer is loading type Cu catalyzer, is made up of Cu active ingredient, auxiliary agent and carrier.The present invention adopts cheap loading type Cu catalyzer, by the preparation condition of clear reaction thing consumption, regulating catalyst and add auxiliary agent thus change the performance of catalyzer, improve the selectivity of reaction; Catalyzer be easy to preparation, with low cost, the selectivity of cyclopropanization reaction mild condition, reaction and the yield of product higher, post catalyst reaction be easy to be separated.Present method is applicable to extensive synthesis 2-thia two ring [3.1.0]-3-hexene-6-manthanoate. |
