Solid-phase synthesis of branched thiohydantoin benzimidazolinethiones and branched thiohydantoin tetrahydroquinoxalinediones

Tetrahedron Letters, 2000
Abstract An efficient solid-phase synthesis method is described for branched thiohydantoin benzimidazolinethiones and branched thiohydantoin tetrahydroquinoxalinediones using 4-fluoro-3-nitrobenzoic acid.

Thiohydantoins. VI. Hydrolysis of 1-acyl-2-thiohydantoins: reported anomalies

Canadian Journal of Chemistry, 1968
Two reports in which it was claimed that the 1-acyl group of a 1-acyl-2-thiohydantoin was not rapidly removed by dilute acid or alkali were investigated and found erroneous.

Thiohydantoins. VII. Ionization and ultraviolet spectra of 4-thiohydantoins and 2,4-dithiohydantoins

Canadian Journal of Chemistry, 1969
The acid and base dissociation constants of 5,5-pentamethylene-4-thiohydantoin, 5,5-pentamethylene-2,4-dithiohydantoin, and their 1-methyl derivatives, have been determined by ultraviolet studies in basic and acid media. In aqueous sulfuric acid the 4-thiohydantoins are protonated on oxygen at the 2-position, so that the extent of protonation varies ...

Thiohydantoins. II. Thiohydantoins Derived from Aspartic and Glutamic Acids

Australian Journal of Scientific Research Series A: Physical Sciences, 1952
N-Acyl derivatives of the &carboxylic acids, aspartic and glutamic acids, yield the corresponding anhydrides when heated with acetic anhydride in the presence or absence of ammonium thiocyanate. In general these anhydrides form isomeric pairs of amides and anilides, and only one of each pair can be converted into the corresponding 2-thiohydantoin ...
