文摘

A procedure was developed for selective opening of the cis-2,4,5-triarylimidazoline ring to form erythro-1,2-diamino-1,2-diarylethane derivatives. These ring-opening products, erythro-ethylenediamine derivatives, can undergo quantitative isomerization to threo-ethylenediamine derivatives in the presence of strong bases in DMSO.
