We have recently described that the α-amino protective groups of L-serine derived nitrones are crucial for the stereoselective course of nucleophilic additions (see ref. 13).

note

In order to simplify calculations, the tert-butoxy group was replaced by a methoxy group and the benzyl group of the nitrone moiety was replaced by a methyl group. Dihedral angles were increased in 10 degrees increments. Also, both dihedral angles β and γ were considered in addition to α in order to ensure that the stationery points given as minima correspond to absolute minima of energy. In fact, for nitrones 5 and 6, three and two conformers very proximal in energy (less than 1 Kcal/mol) were obtained, respectively. Nevertheless, all of them correspond to a model like that depicted in Figure 5 since the only difference stemmed in the values of γ, the rest of parameters being almost identical.

1H NMR spectra of nitrones 4-6 showed the corresponding signals of the NH groups at higher chemical shifts than other NHBoc derivatives (see experimental).
