Abstract
Treatment of the readily available (R)-(-)enantiomer of 2-aminobutan-1-ol 1 with sodium hydride followed by benzyl chloride afforded the O-benzyl base (R)-(-)-2. The latter was successfully used for the resolution of racemic α-methylsuccinic and α-bromosuccinic acids, as well as of the racemic α-benzylhemisuccinic esters 8 and 9 resectively.
