Abstract

The first synthesis of BU-4664L, an actinomycte-produced N-farnesylated dibenzodiazepinone with important biological activities, has been achieved in 18% overall yield from a known benzoic acid derivative by a nine-step sequence that involves an intramolecular Buchwald-Hartwig coupling of a sterically demanding bromo amine intermediate to install the unique tricyclic ring system.
