✦ Synopsis

The final step involves the novel use of mercury (II) acetate for the conversion of thioureas to ureas.

Our desire to develop a novel series of bifunctional chiral auxiliaries, requires the synthesis of C2 symmetric 1,3-diacylimidazolidin-2-onesl.

The availability of truns-1,2diamines such as trans-1,2-diaminocyclohexane la2 and fruns-1,2-diphenyl-1,Zdiarninoethane lb3, coupled with the ease of their resolution4, indicated their suitability as starting materials for such a synthesis. Such an approach would therefore be analogous to the
