摘要：

Diethyl alpha-amino-alpha-alkyl-phosphonates are obtained in good to high enantiomeric excesses by alkylation of chiral phosphonoglycine equivalents embodying the camphor skeleton. The chelating effects in the alkylation step play an important role in enhancing the diastereoselectivity of the reaction as substantiated by semiempirical calculations (AM1).
