Abstract

The reaction of an anionic intermediate, generated in situ from the lithio derivative of 2-(trimethylsilylmethyl)pyridine and an aromatic nitrile, with α-haloketones such as phenacyl bromide, desyl chloride and 2-bromocyclohexanone provided a route to a one-pot synthesis of rare 2-pyridyl substituted furans. The reaction pathway is also described.
