The activated chlorine is readily displaced by nucleophiles. In an interesting synthesis of a fused pyridine, intramolecular cycloaddition is followed by elimination of HCN via a retro-Diels-Alder reaction: Tetrahedron, 44, 2977 (1988).
Selectively metallated at the 3-position by LDA or Li tetramethylpiperidide. The lithio-derivative reacts with electrophiles in good yield: Synthesis, 881 (1988).
