(S)-1,2,4-Butanetriol Usage And Synthesis

Description

(S)-(-)-1,2,4-Butanetriol can be prepared via reduction of (S)-malic acid in the presence of borane-dimethyl sulfide. (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 organic building blocks (+)-3,4-epoxy-1-butanol, (2S,4S)-4-(hydroxymethyl)-2-ferrocenyl-1,3-dioxan, (S)-1,2,4-triacetoxybutane via acetylation with acetic anhydride, and (S)-1,2,4-tris-(3,5-dinitrobenzoy1oxy)butane via esterification with 3,5-dinitrobenzoyl chloride, and so on.

Chemical Properties

clear colorless viscous liquid

Uses

Glycerophospholipids act as regulators of various enzyme activities, and can be used as biological markers to indicate pathological states.

Definition

ChEBI: 2-deoxyerythritol is a secondary alcohol.
