(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.]
