Copper-catalyzed C-H alkoxylation of azoles.
We achieved copper-catalyzed intramolecular and intermolecular alkoxylation of azoles. This reaction is a rare example of transition-metal-catalyzed C-H alkoxylation of heteroaromatic compounds. In addition, the alkoxylation reaction proceeded well even in gram scale. In most intermolecular alkoxylations, the use of an excess amount of alcohols (in some cases, alcohols are used as a solvent) is indispensable to efficiently promote the alkoxylation reaction, but this alkoxylation reaction proceeded using only 1 equiv of alcohols.
