CLEAR YELLOW LIQUID | [Uses]
2-Amino-3-methyl-1-butanol was used in the synthesis of 1-allyl-2-pyrroleimines. It was also used as chiral nucleophile in the total synthesis of benanomicin-pradimicin antibiotics. It was used as homochiral guest compound during synthesis of crown ethers containing two chiral subunits. | [Definition]
ChEBI:2-Amino-3-methyl-1-butanol is an amino alcohol. | [Synthesis]
Example 2: To a dry 12 liter glass reaction vessel (with equipment as described in Example 1) was added 900 grams (7.7 moles) of DL-valine and 2.5 liters of tetrahydrofuran. 1.05 liters (8.5 moles) of boron trifluoride diethyl ether compound and 0.85 liters (8.5 moles) of borane-dimethyl sulfide complex were added sequentially according to the method of Example 1, followed by refluxing. The addition process lasted for 8 hours and heating was continued for 3 hours after the addition was completed. The reaction mixture was quenched with 0.75 liters of tetrahydrofuran/water mixture and subsequently hydrolyzed with 24.6 moles of aqueous sodium hydroxide. The product was separated according to the method described in Example 1, resulting in 494 g (62% yield) of 2-amino-3-methyl-1-butanol having a boiling point of 78°-79°C (8 mm), refractive index n20D 1.4543, and a purity of 97% by gas chromatography (glc) analysis. | [References]
