This review involves chiral metal complexes as catalysts for asymmetric epoxidation of simple olfins. The structure of ligandon metal complexes as catalyst is relevant to its stability, catalytic activity and catalytic efficiency. The enantioselectivity effects are discussed from the point of viewing covering electric, steric factor, configuration of complexes, conformation of transition state and the energy difference between diastereoisomeric intermediares. A brief accounts of mechanics investigation are also given.

Key words: CHIRAL REAGENT, EPOXIDATION REACTION, TRANSITION METAL COMPLEX, ASYMMETRY INDUCTION, CATALYST, ALKENE, CATALYSIS
