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
[Figure not available: see fulltext.] 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 str

Synthesis and crystal structure of new imidazolidine-2,4-dione and imidazolidin-2-one derivatives
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
