Synthesis and evaluation of steroidal thiazoline conjugates as potential antiviral agents.
Future Medicinal Chemistry, 2018AIM Many heterocyclic compounds derived from natural steroids exhibited broad activities, so this work focused on the investigations on a series of steroidal thiazoline conjugates as antiviral agents.

2‐Amino‐2‐thiazoline. V. phenylthioureido and phenylureido derivatives of 2‐thiazoline
Journal of Heterocyclic Chemistry, 1968AbstractThe reaction of 2‐amino‐2‐thiazoline (I) with phenylisothiocyanate has been reported to give 2‐imino‐3‐phenylthiocarbamoylthiazolidine (II) at low temperatures and l‐phenyl‐3‐(2‐thiazolin‐2‐yl)‐2‐thiourea (III) at ca. 100°. When performed by us, however, this reaction gave only a single mono‐adduct regardless of the temperature.

Synthesis of thiazolines and thiazolidines
Chemistry of Heterocyclic Compounds, 1972Primary α-ethynylamines form thiazolines with isothiocyanates, while secondary α-ethynylamines give thiazolidines. Data on the IR, PMR, and UV spectra of the compounds obtained are presented.

Novel synthesis of 2-thiazolines
Tetrahedron Letters, 2000Abstract The synthesis of a series of 2-thiazolines was carried out under mild conditions from the corresponding thiazolidines, by a Ru-catalyzed/TBHP oxidation reaction conditions. The reaction was chemoselective towards the amine-imine oxidation and was also regioselective, affording the unsaturation at the 2-position of the heterocycle, even with ...

Some Conversions of Thiazoline Carboxylic Acid Esters.
ChemInform, 2003We have carried out solvolysis of the previously described ethyl esters of 3-methyl(aryl)-4-methyl-2-thioxothiazoline-5-carboxylic acids, leading to the corresponding acids without breaking down the heterocycle. We synthesized a series of novel esters from the latter by treatment with dimethyl sulfate or reactive halides.

Δ-2 thiazoline et alkyl-2 Δ-2 thiazolines: etude vibrationnelle infrarouge et Raman.conformation
Journal of Molecular Structure, 1978Resume Les spectres Raman (etat liquide) et les spectres infrarouges de la Δ-2 thiazoline et des derives alkyles en position 2 (etats vapeur, liquide, dissous et solide) ont ete examines entre 4000 et 200 cm −1 . L'attribution proposee pour les vibrations fondamentales de ces heterocycles est compatible avec une conformation plane ou tres peu ...

2-Arylimino-3-thiazolines - formation of unusual tautomers of 2-arylamino-thiazolines - a revision
Tetrahedron Letters, 1985Abstract In contrast to previously reported results the products formed in the reaction of arylthioureas with 3-bromomethyl-2-cyanocinnamonitrile are not 2-arylimino- 3-thiazolines but 2-arylamino-4-dicyanomethyl-2-thiazolines.
