, p. 335 - 360 (2007/10/03)
The syntheses of thiazinone, thiazinedione and thiazolinone base modified nucleoside analogues have been discussed in both the deoxy- and ribosyl series. Both inter- and intramolecular N-glycosylations were evaluated.
Sonogashira coupling of functionalized trifloyl oxazoles and thiazoles with terminal alkynes: Synthesis of disubstituted heterocycles
Langille, Neil F.,Dakin, Les A.,Panek, James S.
, p. 2485 - 2488 (2007/10/03)
(Matrix presented) This paper describes Sonogashira cross-coupling of functionalized 2-, 4-, and 5-trifloyl oxazoles and thiazoles with terminal alkynes. This methodology has been extended to 2,4-ditrifloylthiazoles, which results in regioselective cross-coupling at the C2-position of the thiazole. The resulting 2-alkynyl-4-trifloylthiazoles are effective electrophiles in a second palladium(0)-mediated cross-coupling reaction.

, (2008/06/13)
The invention relates to a process for flavouring foodstuffs by incorporating therein an effective amount of at least one compound R1-S-R2 with a specific, well defined structure such as (E)-2-methyl-1-(methylthio)-2-butene; S-ethyl thioformate; S-ethyl-2-(acetylamino)thioacetate; N-(2-methylthioethyl)acetamide; methyl-2-mercaptopropionate; propyl-2-mercaptopropionate; 2-(isopropylthio)pentane; 2-propenylthiol; 4-methyl-2-3H-thiazolone or tautomer; and 2,3-dimethyl-4-formylthiophene. The invention also covers a foodstuff and/or a flavouring concentrate containing at least one of the above identified compounds.

, p. 641 - 645 (2007/10/02)
The reaction of o-aminobenzenethiol with carbonyl sulfide in the presence of triethylamine afforded an alternate route for the synthesis of 2-benzothiazolinone (1) in 97-98percent yield.The reaction of ammonium thiocarbamate (2) with 2-chlorocyclohexanone furnished the novel 4,5,6,7-tetrahydro-2-benzothiazolinone (3). 3-Ethoxy-2H-1,4-benzothiazin-2-one (7) was prepared by the reaction of o-aminobenzenethiol with diethyl oxalate.Possible pathways and supporting nmr, ir and mass spectra are discussed.
