Bifunctional chiral auxiliaries 2: the synthesis of 1,3-diacylimidazolidin-2-ones from 1,2-diamines
摘要:
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.
