Bifunctional Chiral Auxiliaries 5: The Synthesis of 1,3-Diacylimidazolidine-2-thiones and 1,3-Diacylimidazolidin-2-ones from 1,2-Diamines

Although 1,2-diamines fail to cyclise with urea, phosgene or 1,1'-carbonyl diimidazole, they react with carbon disulphide to give the corresponding imidazolidine-2-thiones.These undergo clean diacylation to give 1,3-diacylimidazolidine-2-thiones which are

Bifunctional chiral auxiliaries 2: The synthesis of 1,3-diacylimidazolidin-2-ones from 1,2-diamines

The title compounds are readily prepared in three steps via the corresponding 1,3-diacylimidazolidine-2-thiones. The final step involves the novel use of mercury (II) acetate for the conversion of thioureas to ureas.
