Although there were previously reported methods for enantioselective hydration of allylic alcohols, no equivalent method was up-to-date available for the direct enantioselective functionalization of allylic amines. WebElectrophilic hydration is reversible because an alkene in water is in equilibrium with the alcohol product. To sway the equilibrium one way or another, the temperature or the concentration of the non-nucleophilic strong acid can be changed. For example: Less sulfuric or phosphoric acid and an excess of water help synthesize more alcohol product.
