Improved Synthesis of 2,3-Disubstituted Pyridines by Metallation of 2-Chloropyridine: a Convenient Route to Fused Polyheterocycles

Chemoselective directed metallation of 2-chloropyridine allows the synthesis of 2-substituted 3-carbonylated pyridines, advantage being taken of the metallation ortho-directing effect of the halogen, as well as its reactivity towards nucleophiles.Thus (2-chloro-, 2-methoxy-, and 2-amino-3-pyridyl)-ethanones and -arylmethanones as well as carbaldehydes have been prepared.Some of these ortho-disubstituted intermediates have been readily cyclized to fused polyheterocycles such as naphthiridines and aza-analoges of coumarins, xanthones, and acridones.
