The synthesis of 4,7-dimethoxy 5- and 6-azaindoles, a structural unit that is present in recently developed anti-HIV-1 agents, was achieved in a regioselective manner. The developed strategy is based on the appropriate choice of a protecting group during a lithium-mediated formylation step, followed by thermal cyclization of azidoacrylates.
