The addition reaction of organometallics to chiral α-amino ketones, prepared from α-halo ketones and (S)-2-methoxymethylpyrrolidine as a chiral auxiliary, gave different diastereomers of chiral amino alcohols depending on the difference of coordination ability of the metal used, i.e. organometallics such as Grignardreagent, organozinc, and cerium reagents preferred re-face attack, while organolithium
