T. Yanagi et al., Asymmetric borane reduction of prochiral ketones using aluminum triethoxide and chiral amino alcohols, CHEM LETT, (11), 1999, pp. 1203-1204
The asymmetric borane reduction of prochiral ketones with catalysts prepare
d in situ from aluminum triethoxide and chiral amino alcohols was examined,
and the corresponding chiral alcohols were obtained in high optical purity
