Five-membered Heterocyclic Thiones. Part II. Oxazole-2-thione

Canadian Journal of Chemistry, 1972
Oxazole-2-thione was prepared by the condensation of glycolic aldehyde and thiocyanic acid. It was shown by i.r. spectroscopy that oxazole-2-thione, as well as its 4-methyl- and 4,5-dimethyl derivatives, existed as the thione form in solution.

Thiones as superdipolarophiles

Tetrahedron Letters, 1989
Abstract According to kinetic measurements, the 1,3-cycloadditions of diphenyldiazomethane to thioketones are much faster than those to α,β-unsaturated carbonyl compounds and nitriles previously regarded as record dipolarophiles. The primary cycloadducts are tetrasubstituted 1,3,4-thiadiazolines which extrude N 2 and furnish thiiranes via ...

Synthesis of imidazoline-2-thiones and imidazolidine-2-thiones

Tetrahedron, 1963
Abstract 1-Aryl (or alkyl)-4,5-( d -glucopyrano)imidazolidine-2-thiones are obtained by condensation of 2-amino-2-deoxy- d -glucose with aryl (or alkyl) isothiocyanates. 1-Aryl-4- d - arabino tetrahydroxybutylimidazoline-2-thiones are prepared by reaction of N-arylamino-1-deoxy- d -fructoses with potassium thiocyanate.

HETEROCYCLIC THIONE S-IMIDES AND S-OXIDES. PREPARATION FROM THIONES

Phosphorus and Sulfur and the Related Elements, 1983
Abstract Some six-membered heterocyclic thione S-imides and the corresponding thione S-oxides (sulfines) were prepared from the corresponding thiones. Their stability is briefly discussed.
