(1'S,5R,S)-(1'-phenyleth-1'-yl)-5-iodomethyl-imidazolines 4a, b have been synthesised and easily resolved by silica gel chromatography.The correlation between the configuration and the 1H-NMR chemical shifts allows to assign the configuration at the C-5 of these intermediates.Each pure diastereomer has been converted to R(-)- and to S(+)-1,2-propyldiamine, respectively.
