摘要

Esters of-phenylglycine or substituted phenylglycines, on being stirred with (+)-tartaric acid in alcohols in the presence of carbonyl compounds, give, depending on the reaction conditions, the-or-ester hydrogen (+)-tartrates in up to nearly 100% yield (almost all the racemic ester is converted into the-or-
