(S)-(-)-2-Methyl-1-butanol Chemical Properties,Uses,Production

Chemical Properties

clear colourless liquid

Uses

(S)-(-)-2-Methylbutanol can be used as a reactant to prepare:

Methylbutyl-2-(3-thienyl)acetate (MBTA) by esterification reaction with 3-thiophene acetic acid in the presence of an acid catalyst.
(2S)-2-Methyl-1-butanesulfenyl chloride by reacting with thioacetic acid using Mitsunobu reaction conditions.
(+)-Violapyrone C and (-)-myxalamide A.

Uses

(S)-()-2-Methylbutanol can be used to prepare:

(S)-()-2-Methyl-1-butyloxy carbonyl amino hexyl isocyanate (MBI), which is used to synthesize isocyanate copolymers.
Chiral alkoxynaphathoic acid derivatives having liquid crystalline properties.
3,4-Bis[(S)-2-methylbutoxy]thiophene, a key intermediate for the synthesis of polythiophenes.

Definition

ChEBI: The (S)-enantiomer of 2-methylbutan-1-ol.

General Description

rest mainly 3-methyl-1-butanol

Purification Methods

Reflux the butanol with CaO, distil, reflux with magnesium and again fractionally distil it. A small sample of highly purified material is obtained by fractional crystallisation after conversion into a suitable ester such as the trinitrophthalate or the 3-nitrophthalate. The latter is converted to the cinchonine salt in acetone and recrystallised from CHCl3 by adding pentane. The salt is saponified, extracted with ether, and fractionally distilled. [Terry et al. J Chem Eng Data 5 403 1960, Beilstein 1 IV 1666.]
