Abstract

The resolution of racemic α-hydroxy-H-phosphinic acid with enantiopure 1- phenylethylamines via diastereomeric salt formation was investigated. X-Ray crystallographic analysis of the salt revealed that (R)-1-phenylethylamine to be efficient resolving agent for obtaining a single enantiomer of [α-hydroxy-(o-chlorophenyl) methyl] phosphinic acid. Resolving racemic α-hydroxy-H-phosphinic acid with (S)-2- ...
