ABSTRACT:
The present invention relates to novel synthetic methods for the preparation of indolylquinones. The methods of the present invention are directed to synthetic reactions involving indoles and halo-quinones in solvent and in the presence of a metal carbonate. The invention also relates to bis- and mono-indolylquinones of high purity and pharmaceutical compositions containing the same.
