  Synthesis of amphidinolide Y precursors

  摘要：

  The Negishi coupling between a chiral C3 synthon and an iodoalkene arising from 3-butyn-l-ol, which gave the C3-C9 fragment of amphidinolide Y, was the starting point of a formal total synthesis of this marine natural product. By means of Sharpless ADH and TADDOL-mediated crotylation, the full western fragment (C1-C11) was obtained, which was coupled with the eastern fragment (3-hydroxyoxolane derivative). The penultimate step (ring-closing metathesis, with G-II, H-G-II, or Nitro-Grela reagents, under several conditions) posed great difficulties. The cyclization was achieved with 15c (7,9-bis-O-TES) and 15d (7-O-TES, 9-O-TBS); more than stoichiometric amounts of the H-G-II Ru complex were required for complete conversion.
