reported anionic rearrangement of benzyl 2-pyridyl ethers can now be accessed by a distinct and unusual mechanism: addition of alkyllithium reagents to α-(2-pyridyloxy)-styrene triggers an anionic rearrangement to afford tertiary pyridyl carbinols. The process is explained by invoking a contra-electronic, pyridine-directed carbolithiation of the enolether π-system.
