Asymmetric Synthesis
Asymmetric synthesis, also known as chiral synthesis, enantioselective synthesis, or stereoselective synthesis, is a branch of organic synthesis that studies the chemical reactions that introduce one or more chiral elements to the reactants. In the reaction, the prochiral unit of the substrate molecule interacts with the reactant to form an unequal amount of stereoisomers, and further converts a symmetrical structural unit in the molecule into an asymmetric unit through the reaction, which is called asymmetric synthesis. Asymmetric synthesis plays an important role in drug synthesis and the total synthesis of natural products. However, there is no doubt that the most perfect asymmetric synthesis technology is the enzyme existing in the organism. Whether asymmetric synthesis technology can achieve an efficient catalytic system like enzyme is a challenge to human wisdom.
