  Total synthesis of plagiochins C and D, macrocyclic bis(bibenzyl) constituents of plagiochila acantophylla

  摘要：

  Plagiochins C (3) and D (4) were synthesized by convergent schemes. Rings C and B were joined by Ullman ether synthesis, the aryl-aryl bond between rings A and D was formed by Pd(0)-catalysed coupling of an arylboronic acid (ring D) and a bromobenzoic ester (ring A). Ring C and D were linked by the Wittig reaction, while final ring closure was effected by tetraphenylethene assisted Wurtz reaction.
