4-Hydroxyphenylglycine and 4-fluorophenylglycine can be resolved with (+)-10-camphorsulfonic acid only if dl - or d -(−)-phenylglycine is added. When using dl -phenylglycine this is co-resolved in this process. In this resolution process mixed crys

The asymmetric borane reduction of acetophenone is investigated using mixtures of homochiral β-amino alcohol ligands. With stoichiometric amounts of a mixture of two- or three-amino alcohols, the e.e. remains at the level of the best amino alcohol f
