| titleOfInvention | A kind of preparation method of eight circle heterocyclic rings alkynes |
| abstract | The invention belongs to organic synthesis field, the method for being related to preparing octatomic ring alkynes, the octatomic ring alkynes has following chemical formula: Wherein Ts is p-toluenesulfonyl, the described method comprises the following steps: (a) making compound A In hydroxyl replaced by halogen X, to obtain the first product (b) make first product and compound B Substitution reaction is carried out, the second product is generated Wherein R group is selected from OTBS (tributyl siloxy), OTES (triethyl group siloxy) or OTMS (trim,ethylchlorosilane)；(c) R group is removed from the second product, to obtain third product (d) third product is aoxidized, obtains the 4th product (e) so that the 4th product is carried out annulation, obtain The preparation method is relatively simple, and product purity and yield are higher. |
