Abstract

The synthesis of a new class of angular tetracyclic quinones is described. Our strategy involves Diels-Alder reaction of pyrroloquinolinequinone 9, generated in situ from pyrroloquinoline 8, and dienes. The required pyrroloquinoline 8 was prepared in four steps from commercially available compounds. All compounds were tested for trypanocidal activity in vitro against Trypanosoma cruzi epimastigotes.
