    • The corresponding ethyl ester was prepared from (S)-glutamic acid in a one-pot fashion similar to that reported in reference 3b for the (S)-proline ethyl ester, but the yield was not satisfactory.

    • The data listed in the experimental part are for the major diastereomer and were extracted from spectra of epimeric mixtures as obtained from the chromatography. In some cases we did observe some enrichment after chromatography but not if the weight ratio of silica gel to crude product was kept at 10:1 or less.

    • Gaseous methyl bromide was condensed from a lecture bottle into a dry ice cooled two necked flask with a septum and a cold trap filled with dry ice. A needle was introduced into the septum in order to transfer the reagent to the reaction flask.
