Improved Synthesis of Enantiopure 4-Hydroxy[2.2]paracyclophane

4-Hydroxy[2.2]paracyclophane is readily prepared via an improved synthetic protocol from unsubstituted[2.2]paracyclophane. The key step is a Dakin oxidation of 4-formyl[2.2]paracyclophane. This allows a rapid access to large quantities of the product and an easy synthesis of the enantiopure form.
