Abstract
The olefin cross-metathesis reaction provides a rapid and efficient method for the synthesis of α,β-unsaturated 1,5-dicarbonyl derivatives which then serve as effective precursors to pyridines with a wide range of substitution patterns. High levels of regiocontrol, short reaction sequences, and facile substituent variation are all notable aspects of this methodology.
