A new tetracyclic ring system of biological interest. Indolo[3,2-e][1,2,3]triazolo[1,5-a]pyrimidines through domino reactions of 2-azidoindole

Derivatives of the new ring system indolo[3,2-e][1,2,3]triazolo-[1,5-a]pyrimidine were easily prepared from 2-azidoindole (7) and substituted acetonitriles. Such a cycliczation represents the first example of an anionic domino reaction in the indole serie
