Described herein are catalytic systems that can catalyze enantioselective C—H functionalization reactions and methods of using thereof are described. These catalytic systems contain iron complexes as host catalysts and diammonium guest templates as co-catalysts. The iron-based host catalysts contain crown-ether phthalocyanine ligands. The diammonium guest templates are bidentate compounds with chirality. The iron-based host catalysts and the bidentate ammonium guest templates can provide a complex steric environment with the for stereospecific and site-selective C—H functionalization, such as C—H amination. For example, enantioselective C—H amination reaction performed using the disclosed methods can achieve high enantiomeric ratio (i.e., at least 2:1) and optionally high yield (i.e., at least 30%).
