일반 설명

Chiral reagent.

애플리케이션

(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. 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.

C₂ symmetric chiral diol with versatile applications as a chiral auxiliary, building block, and chiral ligand.
