A variety of novel 1,3-bisacylimidazolidines were prepared in a one-po
t procedure from 1,2-diamines. Condensation of 1,2-diaminoethane or a
selection of chiral 1,2-diamines with a variety of aldehydes under deh
ydrating conditions gives rise to 1,3-bisunsubstituted imidazolidines.
These imidazolidines were not isolated, but were treated with acid ch
lorides or anhydrides to give the novel 1,3-bisacylimidazolidines.
