[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.
[结构:见正文]描述了通过D'芳基硼酸15与CD溴萘醌21的Suzuki偶联合成对应于当归霉素B的CD-D'单元的芳基萘醌22。Suzuki交叉偶联导致22的温和条件可能被证明对于当归霉素B的两个高度功能化的半末端的最终后期偶联是有用的。
