Studies on the Synthesis of the Antitumor Agent CC-1065. Synthesis of the Cyclopropapyrroloindole Portion

Using a regioselective Mannich reaction the 3,3'-bipyrrole (4) is converted into the acid chloride (10), which is transformed into the tricyclic phenol (11); selective reduction of (11) using triethylsilane in trifluoroacetic acid gives (12), which is con
