Jc. Henrion et al., CONDENSATION INDOLE 1,4-NAPHTHOQUINONE - SYNTHESIS OF NEW 2,3-DIINDOLYL-1,4-NAPHTHOQUINONES/, Bulletin des Societes chimiques belges, 105(7), 1996, pp. 403-407
A synthetic pathway to new 2,3-di indolyl-1,4-naphthoquinones is evalu
ated. Access to these structures via the addition of an indole to 1,4-
naphthoquinones, 2-(3-indolyl)-1,4-naphthoquinones or 2,3-disubstitute
d-1,4-naphthoquinones has been studied. New ''symmetrical'' and ''unsy
mmetrical'' 2,3-diindolyl-1,4-naphthoquinones have been prepared.
