  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.

  Bifunctional chiral auxiliaries 5: The synthesis of 1,3-diacylimidazolidine-2-thiones and 1,3-diacylimidazolidin-2-ones from 1,2-diamines

  摘要：

  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 readily converted to 1,3-diacylimidazolidin-2-ones on treatment with mercury (II) acetate. An alternative two-step route to 1,3-diacylimidazolidin-2-ones uses carbonyl sulphide to effect cyclisation of the 1,2-diamine to the imidazolidin-2-one, which is subsequently diacylated. The ability to convert homochiral 1,2-diamines to homochiral 1,3-diacylimidazolidin-2-ones has also been demonstrated.

  An enantioselective borane-mediated deacylation of C2 - symmetrical 1,3-diacetyl-2-imidazolidinethiones, catalyzed by oxazaborolidines derived in situ from an aminoalcohol 2 and borane, provides a promising process for highly effective kinetic resolution.
