Jash M, Das B, Chowdhury C
J Org Chem . 2016 Oct; 81(22):10987-10999. PMID: 27779864
A Pd(II)-catalyzed direct synthesis of benzo[a]carbazoles has been achieved through aminopalladation of alkynes, followed by intramolecular nucleophilic addition of the generated carbon-palladium bond to a tethered cyano/aldehyde group. Compared to...
