Song, Liangliang published the artcileRhodium(III)-catalyzed intermolecular cascade annulation through C-H activation: Concise synthesis of rosettacin, SDS of cas: 1293990-73-4, the publication is Molecular Catalysis (2018), 129-134, database is CAplus.
An intermol. annulation of 2-acetylenic aldehydes or ketones with O-substituted N-hydroxybenzamides or N-hydroxyacrylamides through rhodium(III)-catalyzed C-H activation for the synthesis of isoquinolones and indolizinones is developed. This reaction features excellent functional-group tolerance and broad substrate scope, including annulation of various heterocyclic substrates. This approach evaluates the chemoselectivity of the reaction when sterically hindered diaryl-substituted alkynes are incorporated. This method also furnishes an efficient approach for the total synthesis of rosettacin and a topoisomerase I inhibitor.
