In crystals of N-propylimidazolidinetrione, C6H8N2O3, (I), and N-methyl-N′-phenylethylimidazolidinetrione, C12H12N2O3, (II), the N-alkyl side chains have trans conformations. Photoirradiation of (I) gives the N-allyl derivative both in solution and in the solid state. (II) is photoreactive, yielding a tricyclic compound in solution, but not in the solid state. The photostability of (II) in the crystalline state may be due to the reaction cavity which does not allow the N′-phenylethyl moiety to make a large conformational change for cyclization.
