A new synthetic route to (+/-)-N-2-(Benzenesulfonyl)-CPI (16), the protected A-unit containing a cyclopropylhexadienone moiety of the highly potent antitumor antibiotic CC-1065 (1), from 5-(benzyloxy)-2-bromophenylamine (3) is described. The key steps are a zirconium- and a palladium-initiated cyclization to give the two pyrrole moieties. Reaction of 4a with zirconocene (methyl) chloride leads after workup with I-2 to the 4-iodoindoline 7a, which was transformed into 12 and subsequently via Heck reaction into the pyrroloindoline 15.
