These hydantoin derivatives can be easily synthesized by various methods, most important of these being the BuchererBerg synthesis22,23 (Figure 3), which utilizes the respective aldehydes, potassium cyanide, and ammonium carbonate to synthesize dl-5-substituted hydantoins.
Urech hydantoin synthesis essay
N2 - An improved preparation of 2-polystyrylsulfonamidoethanol resin and its primary application as a polymer support in the synthesis of substituted hydantoin and isoxazoline were reported. A solvent-free synthetic procedure for preparation of 2-polystyrylsulfonamidoethanol resin was optimized by the use of a diffuse reflectance IR spectroscopy technique. Polystyrylsulfonyl chloride (1) was reacted with aminoethanol to yield the 2-polysyrylsulfoamidoethanol Resin 2. Resin 2 was then used as a polymer support in solid phase synthesis of 1-phenylhydantoin and 3-m-nitrophenyl-5-carboxylisoxazoline. The results show that 2-polystyrylsulfonamidoethanol resin is a suitable and useful polymer support.
