Infrarotspektren einiger Thiazoline

Chemische Berichte, 1955
AbstractDie Infrarotspektren von 15 in 2‐Stellung substituierten Thiazolinen wurden aufgenommen. Folgende charakteristische Frequenzen treten auf: a) 6.1–6.45 μ (stark), b) 8.0–8.4 μ (mittelstark bis schwach) und c) 9.8–10.5 μ (stark). Thiazole absorbieren im Bereich a) (6.1–6.45 μ) nur schwach, Thiazolidine nicht.

Tautomeric Modification of GlcNAc-Thiazoline

Organic Letters, 2007
The potent O-GlcNAcase (OGA) inhibitor GlcNAc-thiazoline has been modified by buffer- or acylation-induced imine-to-enamine conversion and then electrophile or radical addition (Xn = D3, F, N3, OH, SMe, COCF3, CF3). Several functionalized GlcNAc-thiazolines show highly selective inhibition of OGA vs human hexosaminidase and thus have promise as tools ...

Synthesis and antioxidant activity of pyrazolyl-oxazolines/thiazolines and isoxazolyl-oxazolines/thiazolines

Medicinal Chemistry Research, 2013
A new class of pyrazolyl/isoxazolyl-oxazolines and thiazolines were synthesized from E-arylsulfonylethenesulfonylacetic acid methyl ester and tested for antioxidant activity. Among the tested compounds, 14b exhibited excellent antioxidant activity when compared with the standard ascorbic acid.

2‐Amino‐2‐thiazoline. V. phenylthioureido and phenylureido derivatives of 2‐thiazoline

Journal of Heterocyclic Chemistry, 1968
AbstractThe 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, 1972
Primary 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, 2000
Abstract 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 ...
