- DPT-mediated synthesis of 2-aminoimidazolidin-4-ones from thioureas tethered to amides
-
2-Aminoimidazolidin-4-ones have been synthesized by using di-2-pyridyl thiocarbonate (DPT), taking the thioureas tethered to amides as the starting materials. Both the primary amides and secondary amides have been subjected to this cyclization method and

- Diversified aminohydantoins from ureas and thioureas tethered to amides
-
Intramolecular cyclization of thioureas or ureas tethered to amides afforded 2-iminohydantoins and 2-amino-1H-imidazol-4(5H)-ones in very high yields (87-100%) regardless of the substituent (alkyls or aryls). This reaction proceeds through carbodiimides a

- Effects of 2-(substituted-sulfanyl)-3,5-dihydro-imidazole-4-one and 2-(Substituted-sulfanyl)-1H-imidazole-4,5-dione derivatives on serum HDL-cholesterol
-
A series of 2-substituted sulfanyl-3,5-dihydro-imidazole-4-ones and 2-substituted sulfanyl-1H-imidazole-4,5-diones was prepared and shown to increase high density lipoprotein cholesterol over other lipid fractions. Compound 1f showed efficacy in additional animal models. The major metabolite of 1f was isolated and its synthesis is reported. The effects of the metabolite on the lipid profile in rats were investigated. (C) 2000 Elsevier Science Ltd. All rights reserved.
