    Synthesis of Chromeno[2,3-d]imidazol-9(1H)-ones via Tandem Reactions of 3-Iodochromones with Amidines Involving Copper-Catalyzed C–H Functionalization and C–O Bond Formation
    摘要:
    A novel six-membered heterocyclic skeleton of imidazochromone was prepared via an efficient one-pot reaction including a key step of copper-catalyzed aerobic C-H intramolecular cycloetherification. Notably, this process does not require the presence of strong para electron-withdrawing groups on the phenol component. Also, the results of this effort show that acyl phenols containing electron-rich heterocycles participate in an efficient C-H activation/C-O formation process.

    A palladium-catalyzed [2 + 2 + 1] domino annulation of 3-iodochromones, α-bromo carbonyl compounds, and tetracyclododecene (TCD) is described. This approach provides a facile, efficient and atom-economical route to a variety of chromone-containing polycyclic compounds bearing fused/bridged-ring systems in good yields (up to 81%) with excellent diastereoselectivities (99 : 1 dr in all cases).
