Notes:
The assignment of meso and dl diastereomers is carried out by NMR analysis of the signals due to the methylene protons in two simple cases, namely, dimethyl α,α′-dibromopimelate (as an acyclic compound) and N-benzyl-2,6-dicarbomethoxypiperidine (as a cyclic compound). In the case of the heterocyclic compound, an nσσ* hyperconjugative interaction between the CH bond α to the heteroatom and the lone pair of the heteroatom can be used, and leads to the same assignment.
