- Preparation of substituted alkoxypyridines via directed metalation and metal-halogen exchange
-
Several halo-substituted alkoxypyridines were prepared and subjected to directed metalation and metal-halogen exchange reactions. The studies resulted in useful methods for synthesis of numerous substituted pyridines via regioselective lithiation, magnesation and halogen dance reactions.
