The Uses of (S)-(+)-2-Amino-1-butanol

(S)-(+)-2-Amino-1-butanol is a chiral amino alcohol that may be used in the synthesis of (S)-2-(6-benzylamino-9-isopropyl-9H-purin-2-ylamino) butan-1-ol, an (S)-enantiomer of roscovitine. It can also be used to synthesize homochiral 2-methylpyrroles. (S)-(+)-2-Amino-1-butanol is an intermediate for the synthesis of (S,S)-ethambutol, an antibacterial agent for treating tuberculosis.

Purification Methods

They are purified by shaking with solid NaOH, filtering and distilling through a short column. The oxalate of the racemate has m 176o. They are strong bases and should be stored under N2 in the absence of CO2. The enantiomers have [] 20 ±12.5o (c 2, EtOH). [Johnson & Degering J Org Chem 8 7 1943, Nagao et al.
