Abstract
A series of 2-diethylphosphono 4-carbethoxy pyrrolidines has been studied by 250 MHz 1H nmr and 13C nmr. A study of the chemical shifts allows us to establish the structures and the analysis of the 3JHH, 3JPH and 3JPC coupling constants leads to designation of preferred conformations for these rings. Good agreement is noted between the angular dependence of these coupling constants and the dihedral angles. [Journal Translation]Keywords
