| titleOfInvention | A kind of method of asymmetric synthesis by chiral acid catalyzed optical voidness terpenoid alkaloid analog |
| abstract | The invention discloses a kind of methods for preparing optical voidness terpenoid alkaloid analog, this method is using aldehyde, p-methylphenyl sulphonylamine as raw material, chiral phosphamide (CPA) is used as catalyst, Magnesium Thiosulfate Hexahydrate is as additive, reaction obtains optical voidness terpenoid alkaloid analog at 0 to -60 DEG C, and reaction equation is (1).The present invention realize it is a kind of by chiral phosphamide be catalyzed polyenoid cyclization come the method for preparing optical voidness terpenoid alkaloid analog, this method is succinctly feasible, and application prospect is extensive. |
