Good combination : Enantioselective enzymatic hydrolysis was combined with a mechanically facilitated racemization process to prepare (S )‐1,1′‐binapthol ((S )‐ binol) in high yield and enantiopurity from a racemic precursor in a single step (see scheme). The enzyme cholesterol esterase stereoselectively hydrolyzes esters of (S )‐ binol and ultrasound was applied to achieve mechanically facilitated racemization of the precursor material.
