for the rapid and efficient construction of highly substituted 3-hydroxypyridines is presented. The thermallyinduced cyclization of easily constructed geminal diazides derived from β-ketoesters having an additional olefin moiety affords the title compounds in yields up to 97% under reagent-free conditions. The new method allows for the synthesis of preparative quantities of material. Additionally
