Chiral Phase Transfer Catalysts

Chiral phase transfer catalysts are a type of catalyst that can promote phase transfer reactions and have chiral centers that can control stereoselectivity in the reaction, thereby achieving asymmetric synthesis. Phase transfer catalysis is a process that can transfer reactants from an immiscible solvent to another phase (for example, from an aqueous phase to an organic phase) for reaction. Chiral phase transfer catalysts add chiral elements to this basis and control the enantioselectivity of the product in the reaction through their chiral centers.
