Electrophilic carbonyl activation: competing condensative cyclizations of tryptamine derivatives [PDF]

open access: yes, 2014
A series of tryptamine derived bisindole substrates were subjected to electrophilic activation of the func-tional grouping at their [alpha]-nitrogen in the form of iminium ions to enable cyclization onto the sterically hindered indole substructure.
