Description
- General description: Chiral reagent.
- Application: (S,S)-(-)-Hydrobenzoin may also be used to prepare (1S,2S,1′S)- and (1S,2S,1′R)-2-(cyclohex-2′-enyloxy)-1,2-diphenylethanol, which are intermediates to prepare enantiopure cyclohexitols.[1] The (S,S)-(-)-hydrobenzoin/Ca complex may be used to catalyze the direct asymmetric aldol reaction of acetophenone and pivalaldehyde to form (R)-3-hydroxy-4,4-dimethyl-1-phenylpentan-1-one.[2]
