Description

General description

(S)-(-)-1,2,4-Butanetriol can be prepared via reduction of (S)-malic acid in the presence of borane-dimethyl sulfide.

Application

(S)-(-)-1,2,4-Butanetriol may be used as a starting material in the enantioselective total syntheses of (+)-azimine and (+)-carpaine.
It can also be used to prepare the following organic building blocks:

• (+)-3,4-epoxy-1-butanol
• (2S,4S)-4-(hydroxymethyl)-2-ferrocenyl-1,3-dioxane
• (S)-1,2,4-triacetoxybutane via acetylation with acetic anhydride
• (S)-1,2,4-tris-(3,5-dinitrobenzoy1oxy)butane via esterification with 3,5-dinitrobenzoyl chloride
