The hydrofluorination of enolizable ynones with AgF in t-BuOH/DMF is reported. The formation of furans as side products can be suppressed using 2,2′-biphenol. The corresponding β-fluoroenones were obtained with good Z-selectivity. A variety of functional groups are tolerated. β-Fluoroenones are vinylogous acid fluorides whose hydrolysis to vinylogous acids can be avoided under the reported reaction conditions. The asymmetric 1,2-reduction of β-fluoroenones to 3-fluoroallylic alcohols is possible with pinacolborane and a Ni(0) catalyst prepared from a pyrimidyloxazoline ligand.

β-(2-Pyridyl) ketones are a unique class of heterocycles with valuable physicochemical properties and emerging relevance as pharmacophores. Herein we report a one-step process for the preparation of various substituted β-(2-pyridyl) ketones from the common starting material, 2,6-lutidine. Furthermore, we demonstrate the utility of this building block by synthesizing of a small set of antimalarial natural products.
An efficient process for the large-scale synthesis of a 2,3,6-trisubstituted indole
Alorati, Anthony D.,Gibb, Andrew D.,Mullens, Peter R.,Stewart, Gavin W.
, p. 1947 - 1952 (2013/03/14)
The efficient synthesis of a key trisubstituted indole intermediate 1 is described. The synthetic route required the use of an aryl Grignard reagent which was not commercially available, and the large-scale formation of this fragment and the thermal evalu
A Weinreb amide approach to the synthesis of trifluoromethylketones

A novel route to access trifluoromethylketones (TFMKs) from Weinreb amides is reported. This represents the first documented case of the Ruppert-Prakash reagent (TMS-CF3) reacting in a constructive manner with an amide and enables synthesis of TMFKs without risk of over-trifluoromethylation.
Improved replicon cellular activity of non-nucleoside allosteric inhibitors of HCV NS5B polymerase: From benzimidazole to indole scaffolds
Beaulieu, Pierre L.,Gillard, James,Bykowski, Darren,Brochu, Christian,Dansereau, Nathalie,Duceppe, Jean-Simon,Hache, Bruno,Jakalian, Araz,Lagace, Lisette,LaPlante, Steven,McKercher, Ginette,Moreau, Elaine,Perreault, Stephane,Stammers, Timothy,Thauvette, Louise,Warrington, Jeff,Kukolj, George

Benzimidazole-based allosteric inhibitors of the hepatitis C virus (HCV) NS5B polymerase were diversified to a variety of topologically related scaffolds. Replacement of the polar benzimidazole core by lipophilic indoles led to inhibitors with improved potency in the cell-based subgenomic HCV replicon system. Transposing the indole scaffold into a previously described series of benzimidazole-tryptophan amides generated the most potent inhibitors of HCV RNA replication in cell culture reported to date in this series (EC50 ~ 50 nM).
A SIMPLE AND EFFECTIVE ENANTIOMERIC SYNTHESIS OF A CHIRAL PRIMARY AMINE
Miao, Clara K.,Sorcek, Ronald,Jones, Paul-James
, p. 2259 - 2262 (2007/10/02)
Catalytic reduction of chiral 2-(2-pyridyl)-1,3-oxazolidines and 2-pyridyl imines derived from (R)-phenylglycinol and (R)-valinol afforded high diastereomeric selectivity.Upon oxidative cleavage, the S-primary amine with high ee was obtained.
