An expedient synthesis of poly-substituted 1-arylisoquinolines from δ-ketonitriles via indium-mediated Barbier reaction protocol
摘要:
We developed an efficient synthetic strategy of poly-substituted 1-arylisoquinolines via an indium-mediated Barbier type allylation from delta-ketonitriles. Initial attack of allylindium species Occurred at the nitrile group selectively to form the enamine intermediate, which reacted with the ketone group intramolecularly to furnish the isoquinolines.

method was developed for poly-substituted naphthalenes via the multi-step, one-pot domino reaction of δ-ketonitriles involving a sequential Michael addition, intramolecular aldol, lactonization, decarboxylative Michael addition, and elimination processes.
