The Uses of 2-Chloro-3-hydroxypyridine
2-Chloro-3-hydroxypyridine has been used in the preparation of 3-hydroxypyridine-2( 1 H)-selone. It has also been used in the synthesis of all four possible benzo[4,5]furopyridine tricyclic heterocycles: benzo[4,5]furo[2,3-b]pyridine, benzo[4,5]furo[2,3-c]pyridine, benzo[4,5]furo[3,2-c]pyridine, and benzo[4,5]furo[3,2-b]pyridine. the synthesis involves α and γ-activation of chloropyridines, as well as palladium-mediated reactions.
