Synthesis of 3-hydroxypyridines using ruthenium-catalyzed ring-closing olefin metathesis
(Chemical Equation Presented) New synthetic routes to substituted 3-hydroxypyridines 6 are presented. Ring-closing olefin metathesis (RCM)/elimination and RCM/oxidation/ deprotection of nitrogen-containing dienes 4 are the key processes of the routes. An
