  A Sequential One-Pot Protocol for the Synthesis of Dihydrobenzo[6,7]indolo-[3′,4′:3,4,5]azepino[2,1-a]isoquinolines Using a Gold-Silver Combined Catalyst

  摘要：

  A sequential one-pot protocol for the synthesis of indole-based peri-annulated polyheterocycles using trifluoroacetic acid and a gold-silver combined catalyst system is described. The reaction is thought to proceed via an imine formation-cationic pi-cyclization-alkyne activation-intramolecular hydroamination sequence to yield novel dihydrobenzo[6,7]indolo[3',4':3,4,5]azepino[2,1-a]isoquinolines in good yields.

  A one pot synthesis of 1H‐benzo[g]indoles, tetrahydrobenzo[h]quinolines, and naphtho[1,2‐b]azepines from 2‐alkynyl benzaldehydes and cyclic amino acids is reported. The salient feature of the strategy involves formation of three new bonds (one CN and two CC bonds) by a metal‐free decarboxylation/cyclization/one‐carbon ring expansion sequence in one pot.

  We describe two simple straightforward syntheses of triazolo isoquinolines (3) and isochromenes (7) from 2-alkynylbenzaldehydes (1) as a common synthon. The synthetic strategy for 3 involves formation of the (E)-1-(2-nitrovinyl)-2-(alkynyl)benzene species 2 via condensation of synthon 1 with nitromethane followed by a [3 + 2] cycloaddition/extrusion of the nitro group/regioselective 6-endo cyclization domino sequence. In yet another strategy, the synthon 1 was condensed with nitromethane followed by electrophilic iodo cyclization of the resulting 2-nitro-1-(2-(alkynyl)phenyl)ethanol (6) to furnish iodo isochromene derivatives. The salient feature of the above two strategies involves formation of the corresponding heterocycles under metal-free conditions in good yields.
