- Copper-catalyzed conversion of aryl and heteroaryl bromides into the corresponding iodide
-
An efficient method for the synthesis of aryl and heteroaryl iodides is described in this study. The reactions of aryl and heteroaryl bromides with potassium iodide proceeded smoothly in the presence of a copper catalyst under mild reaction conditions to produce the corresponding iodides in satisfactory to excellent yields.

- Synthesis and cardiac imaging of 18F-ligands selective for β1-adrenoreceptors
-
A series of potent and selective β1-adrenoreceptor ligands were identified (IC50 range, 0.04-0.25 nM; β1/ β2 selectivity range, 65-450-fold), labeled with the PET radioisotope fluorine-18 and evaluated in normal Sprague-Dawley rats. Tissue distribution studies demonstrated uptake of each radiotracers from the blood pool into the myocardium (0.48-0.62% ID/g), lung (0.63-0.97% ID/g), and liver (1.03-1.14% ID/g). Dynamic μPET imaging confirmed the in vivo dissection studies.

- Selective catalytic hydrogenation of nitro groups in the presence of activated heteroaryl halides
-
Chemoselective reduction of nitro groups in the presence of activated heteroaryl halides was achieved via catalytic hydrogenation with a commercially available sulfided platinum catalyst. The optimized conditions employ low temperature, pressure, and catalyst loading (0.1 mol % Pt) to afford heteroaromatic amines with minimal hydrodehalogenation byproducts.

- A practical iodination of aromatic compounds by using iodine and iodic acid
-
This article describes simple and efficient method for the iodination of different aromatic amines, hydroxy aromatic aldehydes, hydroxy acetophenones and phenols using iodine and iodic acid in ethanol as a solvent. Notable advantages include mild reaction condition, no need of catalyst, short reaction time, simple practical procedure, giving excellent yield of the product. Copyright Taylor & Francis Group, LLC.

- A revised synthesis of the antitumour antibiotic L-azatyrosine via 2-iodo-5-methoxypyridine
-
A revised synthesis of the antitumour antibiotic L-azatyrosine is reported, the main features of which are the unambiguous synthesis of the previously misinterpreted 2-iodo-5-methoxypyridine and subsequent palladium-catalysed coupling with an iodoalanine-derived zinc reagent.
