Carboxamido groups are introduced into the 6-position of 3-acylpyridines with high regioselectivity via Minisci reaction with formamides, Fe(II) sulfate and tert-butyl hydroperoxide.The isolation procedure is considerably improved by the addition of citric acid for complexation of the Fe ions.Fusaric acid and other 5-alkyl-2-pyridine carboxylic acids are obtained by a following Wolff-Kishner reaction in 20-75percent overall yield.

Reaction of aryl pyridyl ketones 1 with vinylmagnesium bromide followed by acetylation of the products 2 with acetic anhydride/Et3N and with 4-(dimethylamino)pyridine (DMAP) as a catalyst gave acetates 3 in high yields.Treatment of acetates 3 with dimethylamine in the presence of a palladium catalyst produced a mixture of E and Z isomers of 3-aryl-3-pyridylallylamines 4.

, p. 1495 - 1501 (2007/10/05)
A series of compounds with general structure Het CO Ar CH(CH3)COOH was prepared for pharmacological screening. Different synthetic approaches are described. α Methyl 4 (2 thienylcarbonyl)benzeneacetic acid (compound III-l, suprofen), was found to show a marked antiwrithing activity. Furthermore this compound proved to be a potent inhibitor of prostaglandin biosynthesis.
