英文摘要： Focused on catalytic asymmetric core issues of efficiency and selectivity, a series of novel chiral metal complex catalysts, the metal-organic bifunctional catalysts and the organic molecules bifunctional catalysts will be designed and synthesized in this research project. According to the matching relationship between chiral ligand, metal and substrate or chiral organic molecule and substrate, asymmetric tandem cyclization reactions and concerted cyclization reactions, such as cascade Michael-Michael cyclization, tandem Michael-Aldol cyclization, Povarov cyclization, cycloaddition reaction, hetereo-Diels-Alder reaction etc., will be carefully selected and developed in order to furnish the corresponding optically avtive multistereogenic cyclohexanones, pyrroles, pyrazolidine, tetrahydropyridines, tetrahydropyran ketones, quinolines, spirocyclic oxindoles with excellent yields, enantioselectivities and diastereoselectivities. On the basis of synthesis of those potentially biological and pharmacological active carbocyclic, heterocyclic, spirocyclic, and the bridged ring compounds, it is another important task that exploring and understanding the scientific regulation of chiral induction, transmission and amplification in this research project. Finally, the biological and pharmacological activity will be preliminar
