The absolute configuration of Bz-product 4e was determined after transformation into the stereochemically known N-benzoylphenylglycine methyl ester. The stereochemical determination of 4a and the experimental procedure for derivatization of 4 to N-protected glycine methyl ester were described in ref. 8a.
