Londregan, Allyn T.,Storer, Gregory,Wooten, Ceshea,Yang, Xiaojing,Warmus, Joseph
supporting information; experimental part, p. 1986 - 1988 (2009/07/05)
Dehydrative amide couplings with 2-pyridylamines suffer from variable yields. A mild and high-yielding synthesis of N-(pyridin-2-yl)amides employing 2-aminopyridine-N-oxides is presented as a solution.

7-Azaindoles via carbolithiation of vinyl pyridines
Cottineau, Bertrand,O'Shea, Donal F.
, p. 10354 - 10362 (2008/02/13)
The sequential reactions of a pyridine vinylation and alkene carbolithiation constitutes a new route to substituted 7-azaindoles. The methodology involves a reaction sequence of controlled carbolithiation of the vinyl double bond, subsequent trapping of t
Regiospecific Electrophilic Substitution of Aminopyridines: Ortho Lithiation of 2-, 3-, and 4-(Pivaloylamino)pyridines
Turner, James A.
, p. 3401 - 3408 (2007/10/02)
2- and 4-(pivaloylamino)pyridines have been shown to undergo metalation exclusively at C-3 and these smoothly react with a variety of electrophiles to produce 2,3- and 3,4-disubstituted pyridines, respectively.Removal of the pivaloyl protecting group results in overall electrophilic substitution of an aminopyridine.Utilization of this method is exemplified by efficient syntheses of 2- and 4-aminonicotinaldehydes.Minor modifications of the reaction conditions permitted exclusive ortho metalation of 2-(pivaloylamino)pyridines additionally functionalized by chloro, fluoro, or methyl groups.Although the major product from reaction of 3-(pivaloylamino)pyridine by this method was metalation at C-4, the reaction was complicated by substantial quantities of product derived from nucleophilic attack by n-butyllithium on the pyridine nucleus.
