  Single-stage synthesis of 3-hydroxy- and 3-alkoxy-5-arylimidazolidine-2,4-diones by reaction of arylglyoxal hydrates with N-hydroxy- and N-alkoxyureas

  摘要：

  Arylglyoxal hydrates interact with N-alkoxyureas and N-hydroxyurea in acetic acid with selective formation of 3-alkoxy-5-arylimidazolidine-2,4-diones and 5-aryl-3-hydroxyimidazolidine-2,4-diones, respectively. The structures of 3-methoxy-5-phenylimidazolidine-2,4-dione, 3-ethoxy-5-phenylimidazolidine-2,4-dione, and 3-butoxy-5-(4-chlorophenyl)imidazolidine-2,4-dione were studied by X-ray structural analysis.

  Arylglyoxals condense with N-hydroxyurea in water via intermediate formation of N-hydroxy-N-[hydroxy(aroyl)]methylureas and 3,4,5-trihydroxy-5-arylimidazolidin-2-ones to yield 3-hydroxy-5-aryl-imidazolidine-2,4-diones as end products; the 3,4,5-trihydroxy-5-(p-chlorophenyl)imidazolidin-2-one and 3-hydroxy-5-phenylimidazolidine-2,4-dione crystallise as racemates.
