| titleOfInvention | A kind of 5/6/7/6 tetracyclic compound with fused benzene ring and its synthetic method |
| abstract | The invention discloses a 5/6/7/6 tetracyclic compound fused with benzene rings and a synthesis method thereof. The raw material is o-alkynyl benzaldehyde compound connected with cyclohexadienone propargyl ether, and a platinum catalyst is used. Under the catalysis, the reaction is heated in the solvent THF, and the 5/6/7/6 tetracyclic compound with fused benzene rings is obtained after post-treatment. The present invention provides a new synthetic method for 5/6/7/6 tetracyclic compounds fused with benzene rings which cannot be easily prepared by conventional methods, which can construct four consecutive chiral centers in one step and has excellent stereoselectivity; The inventive method has the advantages of simple operation, wide substrate range, high yield and the like. |
