Transition metal mediated selective C vs N arylation of 2-aminonaphthoquinone and its application toward the synthesis of benzocarbazoledione
摘要:
Selective C vs N-arylation of 2-aminonaphthoquinone was achieved using different transition metal salts and arylboronic acids. Mn(OAc)(3)center dot 2H(2)O provided C-arylated product whereas NiCl2 center dot 6H(2)O and Cu (OAc)(2)center dot H2O provided N-mono arylated and N,N-diarylated products respectively. Usefulness of the C and N arylated product was demonstrated by converting it into benzocarbazoledione. (C) 2017 Elsevier Ltd. All rights reserved.
