A series of novel 2-thioxoimidazolidine glycosides were prepared via reaction of the key intermediate 2-(benzylsulfanyl)-5-[4-(3-hydroxypropoxy)-3-(methoxybenzylidene)]-3-phenyl-1H-imidazol-4-one with different sugar aldose or sugar hydrazones to give the corresponding glycosides. The newly synthesized compounds were confirmed by physical and spectral data.

A variety of novel 5-[( Z )-arylidene]-2-[(2-( E )-arylidene)hydrazono]-4-imidazolidinones 1a-c to 4a , b and 5-[( Z )-arylidene]-2-[(2-( E )-polyhydroxyalkylidene)hydrazono]-4-imidazolidinones 5a-c to 7a-c were prepared from the reaction of 5-[( Z )-arylidene]-2-methylmercaptohydantoins 8a-c with 2-( E )-arylidene hydrazones 13a-d and/or 2-( E )-monosaccharides hydrazones 16a-c .

rapid and the latter preponderate; exceptions are the hydrazones of d -ribose and l -arabinose which give almost equal proportions of acyclic and cyclic tautomers at pH 6. Reaction of representative saccharide hydrazones with nitrousacid gives a mixture of the corresponding saccharide and the β-glycosyl azide, the latter being formed from the glycosylhydrazine tautomer.
A series of 5-[(Z)-(4-(2-(E)-arylidene)hydrazonosulfonylbenzylidene)]-2, 4-imidazolidinediones 6a-h and 5-[(Z)-(4-(2-beta-D-glycopyranosyl) hydrazinosulfonylbenzylidene)]-2,4-imidazolidinediones 10a-j were synthesized via two different routes. The compounds did not display any antiviral and antitumoral activity.
