[structure: see text] A synthesis of arylnaphthoquinone 22 corresponding to the CD-D' unit of angelmicin B via the Suzuki coupling of the D' arylboronic acid 15 with the CD bromonaphthoquinone 21 is described. The mild conditions for the Suzuki cross-coupling leading to 22 may prove to be useful for the eventual late-stage coupling of the two highly functionalized halves of angelmicin B.
