  Scaffold-Divergent Synthesis of Ring-Fused Indoles, Quinolines, and Quinolones via Iodonium-Induced Reaction Cascades

  摘要：

  N-(2-lodophenyl)imines A are readily formed from Schiff's base condensation of 2-iodoanilines with carbonyls and ketals. These imines provide useful substrates in scaffold-divergent synthesis through the attachment of an alkyne (Songashira coupling or acyl substitution of a Weinreb amide) followed by an iodonium-induced reaction cascade to give ring-fused indoles B, quinolines C, or quinolones D depending on the reaction conditions employed.

  A method for the synthesis of 2,3-dihydrofuro[3,2-c]quinolines via TfOH or TMSOTf mediated condensation of 2-aminoaryl cyclopropyl ketones with aldehydes has been developed. The reaction proceeds under transition metal or halogen free conditions, giving access to the target molecules in 27-90% isolated yields. Mechanistic study indicates that the reaction sequence involves imine formation, intramolecular

  An efficient Ru-catalyzed synthesis of dihydrofuroquinolines from azido-cyclopropyl ketones via the reduction-cyclization-rearrangement process is reported. A plausible reaction mechanism for this process is depicted. Additionally, when the reaction was carried out under H-2 (1 atm) In the presence of Pd/C, 4-quinolones were obtained in excellent yields.

  A simple two-step convergent protocol gives direct access to synthetic intermediate A from ortho-iodoanilines. Intermediate A can be treated with NIS in CH(2)Cl(2) to induce novel iodonium mediated domino reaction cascade, which provides direct access to ring-fused indole compounds B. Simply by changing the reaction conditions, this protocol can be directed down an alternative domino reaction cascade to give various ring fused quinoline compounds C.
