Solid phase synthesis of pyridine-based derivatives from a 2-chloro-5-bromopyridine scaffold.
2-Chloro-5-bromopyridine was immobilized on polystyrene via selective introduction of a traceless silicon linker at the C-4 position. A useful scaffold was thus obtained, as demonstrated by efficient and selective reactions with polar and transition organometallic reagents, opening a new access to pyridine-based libraries of synthons and chromophores.
