Abstract: PURPOSE: A bichromene or biquinoline derivative and a method for preparing the same are provided to synthesize derivatives of high purity with high yield. CONSTITUTION: A method for preparing a compound of chemical formula 1 comprises a step of cyclizing a compound of chemical formula 3 under the presence of a gold catalyst, a silver catalyst, or a mixture thereof. The gold catalyst includes AuCl, AuCl_, Ph_PAuCl, (C_6F_5)_3PAuCl, (4-CF_3-C_6H_4)_3PAuCl, IMesAuCl(IMes : 1,3-bis(2,4,6-trimethylphenyl)imidazol-2- ylidene), IPrAuCl(IPr : 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene), or Au(JohnPhos)Cl(JohnPhos : (2-biphenyl)di-tert-butylphosphine). The silver catalyst is AgOTf, AgNTf_2, AgSbF_6, AgAsF_6, AgBF_4, or AgNO_3. The cyclization is performed in a solvent of dichloromethane(DCM), dichloroethane(DCE), toluene, acetonitrile, nitromethane, tetrahydrofurane(THF), N,N-dimethylformamide(DMF), or N,N-dimethyl acetamide(DMA).
