The total synthesis of plagiochin D, a macrocyclic bis(bibenzyl) compound isolated from the liverwort plagiochila acanthophylla, has been accomplished. Closure of the key 16-membered ring, which contained biphenyl ether and biaryl units, was achieved in good yield by an intramolecular SNAr reaction. The Suzuki and Wittig protocols proved to be powerful tools for the construction of a linear precursor
plagiochin D 是一种大环双(联苄基)化合物,它是从地草 plagiochila acanthophylla 中分离出来的,已完成全合成。通过分子内 SNAr 反应以良好的收率实现了包含联苯醚和联芳基单元的关键 16 元环的闭合。Suzuki 和 Wittig 方案被证明是构建线性前体的有力工具,该前体对环环化至关重要。
