Abstract

Nitrogen heterocyclic compounds occupy a very important role in synthetic organic chemistry because of the useful properties of many members of this class of compounds.(1) Over 50 naturally occurring alkaloids containing the 2,2′-biindole subunit have been isolated and characterized.(2) This subunit is stable and can be found in a vast number of biologically active natural products such as the tjipanazoles, staurosporine, ent-staurosporine, holyrine, ...
