supporting information; experimental part, p. 9078 - 9081 (2012/07/13)
An efficient and general method for the synthesis of 1,4-dihydropyridines and pyridines based on a lithiation/isomerization/intramolecular carbolithiation sequence is reported. This procedure provides an efficient, divergent, and straightforward entry to a wide range of polysubstituted dihydropyridines and pyridines starting from readily available N-allyl-ynamides.
Intramolecular carbolithiation of N-allyl-ynamides: An efficient entry to 1,4-dihydropyridines and pyridines - Application to a formal synthesis of sarizotan

We have developed a general synthesis of polysubstituted 1,4-dihydropyridines and pyridines based on a highly regioselective lithiation/6-endo-dig intramolecular carbolithiation from readily available N-allyl-ynamides. This reaction, which has been successfully applied to the formal synthesis of the anti-dyskinesia agent sarizotan, further extends the use of ynamides in organic synthesis and further demonstrates the synthetic efficiency of carbometallation reactions.

4-(2-Ethynylphenyl)pyridine (10), 3-(2-ethynylphenyl)pyridine (11), 2-(2-trimethylsilylethynylphenyl)pyridine (26), and 3-ethynyl-2-phenylpyridine (13) were prepared from readily available pyridine precursors by standard coupling reactions. Pyrolysis of 10 at 810 °C/0.5 Torr provided benzo[f]isoquinoline (45) and the benzopentalene dimer 47. Pyrolysis of 11 (820 °C/0.5 Torr) afforded benzo[f]quinoline (50), benzo[h]i-soquinoline (52), and a mixture of isomers of 47. Pyrolysis of 13 (820 °C/0.3 Torr) provided benzo[h]quinoline (56) and the novel azulene derivative azuleno[1,2-b]pyridine (58). When 26 was desilylated by treatment with TBAF in THF/water, the unusual "dimerization" product 37 was produced; its structure was confirmed by X-ray structural analysis. The mechanisms of these transformations are discussed. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.
THE PYRIDYL CATION AS A REACTIVE INTERMEDIATE IN THE PHOTOREACTION OF IODOPYRIDINES WITH BENZENES

, p. 3433 - 3436 (2007/10/02)
The electrophilic behavior of the reactive entity in the photosubstitution of benzenes with 2-iodopyridine was found to be ascribable to the intermediary 2-pyridyl cation, rather than the electrophilic 2-pyridyl radical.
A CONVENIENT SYNTHESIS OF 3-ARYLPYRIDINES BY THE PALLADIUM CATALYZED COUPLING REACTION OF DIETHYL(3-PYRIDYL)BORANE WITH ARYL HALIDES
Ishikura, Minoru,Kamada, Machiko,Terashima, Masanao
, p. 265 - 268 (2007/10/02)
The utilization of heteroarylborane to the preparation of a variety of 3-arylpyridines by the palladium catalyzed cross coupling reaction between diethyl(3-pyridyl)borane and aryl halides in the presence of bases is described.
