  Total synthesis of Plagiochin D, a macrocyclic bis(bibenzyl) from liverworts by intramolecular Still-Kelly reaction

  摘要：

  Plagiochin D (4), a unique macrocyclic bis(bibenzyl) having both a biphenyl ether and a biaryl units isolated from the liverwort Plagiochila acanthophylla, was synthesized. The key 16-membered ring closure of a dibromoperrottetin A derivative 13 was realized by Pd(0) catalyzed intramolecular Still-Kelly reaction. (C) 1998 Elsevier Science Ltd. All rights reserved.

  Total syntheses of plagiochins A (1) and D (4), the former of which exhibits a significant neurotrophic activity, have been accomplished. The key 16-membered ring closure in 4 has been achieved directly from the dibromoperrottetin derivative (7) by Pd(0) catalyzed intramolecular Stille-Kelly reaction, whereas 1 has been synthesized from the dibromide (28) via the trimethylstannyl compounds (29) and (30) by Pd(0) catalyzed intramolecular Stille reaction.
