Functionalization with C1-building blocks are key synthetic methods in organic synthesis. The low reactivity of the most abundant C1-molecule, carbon dioxide, makes alternative carboxylation reactions with CO2-surrogates especially important. We report a photoredox-catalyzed protocol for alkene carbamoylations. Readily accessible 4-carboxamido-Hantzsch esters serve as convenient starting materials that generate carbamoyl radicals upon visible light-mediated single-electron transfer. Addition to various alkenes proceeded with high levels of regio- and chemoselectivity.

Altundas, Aliye,Ayvaz, Selcuk,Logoglu, Elif
experimental part, p. 1 - 8 (2012/02/04)
With the aim of developing potential antimicrobials, a series of 2-amino-3-cyanopyridines incorporating both sulfur and oxygen as part of the heteroaromatic ring (methyl thiophene, methyl furan) and fused cycloalkane groups were synthesized and characterized by FTIR, 1H-NMR, 13C-NMR, and bases of elemental analysis. All synthesized compounds were evaluated for their in vitro antibacterial and antifungal activity. Antibacterial and antifungal activities of aminocyanopyridines against Pseudomonas aeruginosa ATCC 29212, Bacillus subtilis RSKK 244, Bacillus megaterium (clinical isolate), the gram-positive bacterium Micrococcus luteus NRRLB 4375, and the fungus Candida albicans ATCC 90028 were studied. The relationship between the functional-group variation and the biological activity of the evaluated compounds is discussed. Birkhaeuser Boston 2010.

A2A adenosine receptor antagonists usually have bi- or tricyclic N aromatic systems with varying substitution patterns to achieve desired receptor affinity and selectivity. Using a pharmacophore model designed by overlap of nonxanthine type of previously known A2A antagonists, we synthesized a new class of compounds having a 2-amino nicotinonitrile core moiety. From our data, we conclude that the presence of at least one furan group rather than phenyl is beneficial for high affinity on the A2A adenosine receptor. Compounds 39 (LUF6050) and 44 (LUF6080) of the series had Ki values of 1.4 and 1.0 nM, respectively, with reasonable selectivity toward the other adenosine receptor subtypes, A1, A 2B, and A3. The high affinity of 44 was corroborated in a cAMP second messenger assay, yielding subnanomolar potency for this compound.
