Reaction of a 3-aryilidene-2-thiohydantoin derivative with polymeric trans-[CuCl2(DMSO)2]n complex: Unexpected isomerization to dinuclear cis-[{CuCl(DMSO)2}(μ-Cl)]2 [PDF]
The 3-arylidene-2-thiohydantoin derivative, 3-[(2-hydroxybenzylidene) amino]-2-thioxoimidazolidin-4-one, was synthesized in a two-step condensation reaction of 2-hydroxybenzaldehyde, thiosemicarbazide and ethyl chloroacetate.

1-Acetyl-2-thiohydantoin [PDF]
In the title compound (1-acetyl-4-oxoimidazolidine-2-thione, C5H6N2O2S), the plane of the acetyl group forms an angle of 6.7° with the essentially planar thiohydantoin ring. N—H⋯O hydrogen bonds create quasiplanar chains of molecules along the y axis.

Synthesis and Identification of Heterobivalent Anticancer Compounds Containing Urea and 5-Arylidene-2-Thiohydantoin Motifs. [PDF]
A synthetic approach to the synthesis of novel heterobivalent compounds containing urea and 5‐arylthiohydantoin groups was developed for the preparation of a mixture‐based library. Through the screening and deconvolution of the library, six hits with βC branched residues at R1 and imidazyl residue at R3 were identified exhibiting moderate inhibitory ...

A Plausible Prebiotic One-Pot Synthesis of Orotate and Pyruvate Suggestive of Common Protometabolic Pathways. [PDF]
A prebiotic synthesis of the nucleobase orotate, and the citric acid cycle intermediate pyruvate, proceeds in a single pot from two small glycine derivatives, hydantoin and glyoxylate, under mild aqueous conditions. These findings support a co‐evolution of pathways to core protometabolites and nucleic acid building blocks in a common environment ...

Efforst are described for developing Brønsted base‐catalyzed, site‐ and stereoselective α‐functionalization of a variety of unsaturated enolizable carbonyl compounds via transient enolates featuring an extended π‐system. Abstract Chiral Brønsted base (BB) catalyzed asymmetric transformations constitute an important tool for synthesis.
