7-Dialkylamino-1-alkylquinolinium salts: Highly versatile and stable fluorescent probes
Van Den Berg, Otto,Jager, Wolter F.,Picken, Stephen J.
, p. 2666 - 2676 (2006)
7-Dialkylamino- and 7-alkylsulfenyl-1-alkylquinolinium salts have been synthesized using a novel synthetic approach. The key intermediate, 7-fluoro-1-methylquinolinium iodide, was shown to possess high reactivity toward nitrogen and sulfur nucleophiles, a

The bromodomain and plant homeodomain finger-containing (BRPF) family are scaffolding proteins important for the recruitment of histone acetyltransferases of the MYST family to chromatin. Here, we describe NI-57 (16) as new pan-BRPF chemical probe of the bromodomain (BRD) of the BRPFs. Inhibitor 16 preferentially bound the BRD of BRPF1 and BRPF2 over BRPF3, whereas binding to BRD9 was weaker. Compound 16 has excellent selectivity over nonclass IV BRD proteins. Target engagement of BRPF1B and BRPF2 with 16 was demonstrated in nanoBRET and FRAP assays. The binding of 16 to BRPF1B was rationalized through an X-ray cocrystal structure determination, which showed a flipped binding orientation when compared to previous structures. We report studies that show 16 has functional activity in cellular assays by modulation of the phenotype at low micromolar concentrations in both cancer and inflammatory models. Pharmacokinetic data for 16 was generated in mouse with single dose administration showing favorable oral bioavailability.
Pd-catalyzed nucleophilic fluorination of aryl bromides

On the basis of mechanism-driven reaction design, a Pd-catalyzed nucleophilic fluorination of aryl bromides and iodides has been developed. The method exhibits a broad substrate scope, especially with respect to nitrogen-containing heteroaryl bromides, and proceeds with minimal formation of the corresponding reduction products. A facilitated ligand modification process was shown to be critical to the success of the reaction.

A novel improvement in ArLPdF catalytic fluorination of aromatic compounds
Samant, Bhupesh S.,Bhagwat, Sunil S.
experimental part, p. 191 - 194 (2012/01/05)
In this study, we used reverse micellar medium for overcoming the disadvantages of ArLMF catalytic fluorination of aromatic compounds. It not only enhanced the fluorination rate, but also widened the scope of reaction for bromoaromatics with electron donating and withdrawing functionalities at ortho position. Various bromoaromatic compounds were fluorinated using the biarylphosphine ligand i.e. cyclohexyl BrettPhos ligand, along with [cinnamylPdCl]2, and CsF as the fluoride source in reverse micellar media. The anisotropic palisade layer of reverse micelles provided the active site for reaction. The most crucial factor in the critical reductive elimination step could be the spatial orientation of ArLPdF complex in the palisade layer; forming ArF as the final product in high yield with excellent selectivity.
Accelerating palladium-catalyzed C-F bond formation: Use of a microflow packed-bed reactor
Noel, Timothy,Maimone, Thomas J.,Buchwald, Stephen L.
supporting information; experimental part, p. 8900 - 8903 (2011/10/19)
A flow process for Pd-catalyzed C-F bond formation is described. A microreactor with a packed-bed design allows for easy handling of large quantities of insoluble CsF with precise control over reaction times, efficient mixing, and the ability to safely handle elevated temperatures and pressures. A variety of aryl triflates, including heteroaryl ones, were converted into aryl fluorides in short reaction times (see scheme).
