Thiazoles are important heterocyclic motifs in many target molecules. Extension of a reported gold(I)-catalyzed oxidative coupling of alkynes and thioamides to the synthesis of functionalized thiazole-containing products is presented, including the compatibility of this reaction with ester, protected hydroxyl, alkene and thioether groups. The utility of this one-pot process is demonstrated in the preparation of the thiazole-containing macrodiolide of a simplified analogue of pateamine A.
Microwave-assisted synthesis of potent PDE7 inhibitors containing a thienopyrimidin-4-amine scaffold
Sanchez, Ana I.,Meneses, Ricardo,Minguez, Jose M.,Nunez, Araceli,Castillo, Rafael R.,Filace, Fabiana,Burgos, Carolina,Vaquero, Juan J.,Alvarez-Builla, Julio,Cortes-Cabrera, Alvaro,Gago, Federico,Terricabras, Emma,Segarra, Victor

A series of novel thienopyrimidin-4-amines have been synthesized and evaluated as phosphodiesterase (PDE) inhibitors. A rationale for the observed selectivity against PDE7 has been obtained from molecular modelling studies on the most active compounds. This journal is the Partner Organisations 2014.

Mahammed,Jayashankara,Premsai Rai,Mohana Raju,Arunachalam
experimental part, p. 2338 - 2340 (2009/12/08)
Aliphatic and aromatic nitriles react with thioacetic acid in the presence of calcium hydride to give the corresponding thioamides in good to excellent yields. The examples studied include haloaryl nitriles in which the halogen is facile towards SNAr reactions under other conditions. Georg Thieme Verlag Stuttgart.

Palladium-catalyzed cyclization-methoxycarbonylation of (2R,3S)-3-methylpent-4-yne-1,2-diol (6) derived from (2R,3S)-epoxybutanoate 5 followed by methylation gave the tetrahydro-2-furylidene acetate (-)-7, which was converted to the left-half aldehyde (+)-3. A Wittig reaction between (+)-3 and the phosphoranylide derived from the bithiazole-type phosphonium iodide 4 using lithium bis(trimethylsilyl)amide afforded the (+)-cystothiazole G (2), whose spectral data were identical with those of the natural product (+)-2. Thus, the stereochemistry of cystothiazole G (2) was proved to be (4R,5S,6(E)).

, p. 863 - 869 (2007/10/03)
The synthesis of a series of new (99m)Tc-thioamide complexes with the [Tc=N]2+ nitrido core, in which the thioamide ligand substituents were varied to include different lengths of atiphatic alkyl chains or a phenyl group is reported. TLC analysis shows that the complexes are neutral and lipophilic compounds. The (99m)Tc complexes have a low blood cell labelling efficiency in whole blood compared to the reference complex of dithiocarbamate (99m)TcN(Et(EtO)NCS2)2.
A new method for converting nitriles into primary thioamides by sodium trimethylsilanethiolate
Lin,Ku,Shiao
, p. 1219 - 1220 (2007/10/02)
A new method was developed for converting nitriles into primary thioamides. Treatment of various nitriles 1 with 1.5-2.5 equivalents of sodium trimethylsilyl sulfide (sodium trimethylsilanethiolate) in 1,3-dimethyl-2-imidazolidinone at 20-35°C for 4-30 hours gave the corresponding thioamides 2 in 27-80% yield.
