                                摘要:
                                D-Alloisoleucine was obtained from L-isoleucine by acetylation and epimerization by acetic anhydride followed by separation of the diastereoisomeric ammonium salts using the solubility difference. The structure-solubility relationship of diastereoisomeric salts was explained by X-ray crystal structure analysis. (C) 2008 Elsevier Ltd.
