  Exploration of conjugate addition routes to advanced tricyclic components of mangicol A

  摘要：

  Two synthetic approaches to the cytotoxic marine natural product known as mangicol A are described. The starting material common to both pathways is the cyclopentenonecarboxylate 11. The first tactic involves the 1,4-addition to 11 of the cuprate derivable from iodide 10, while the second proceeds via base-promoted conjugate addition of the regiospecifically generated enolate anion of 41. The first strategy proceeds by a series of efficient steps to tricyclic aldol 21 and subsequently to beta-diketone 7. The latter proved to be totally unresponsive to schemes aimed at introduction of a butenyl group. The second approach involves earlier introduction of this substituent as realized in stereo-controlled fashion via transition state 42. While further passage to 44 proved uneventful, this advanced intermediate and analogs thereof proved remarkably recalcitrant to cyclization in the precedented fashion. In no instance was generation of a suitable product realized. These studies serve to underscore the extent to which steric considerations can complicate matters and the extent to which they must be skirted. Finally, a direct enantioselective route to the side chain aldehyde 2 is detailed. (c) 2006 Elsevier Ltd. All rights reserved.

  The first enantioselective total syntheses of (−)-caulamidine D (5) and (−)-isocaulamidine D (6) were accomplished. Their absolute configurations were unambiguously elucidated through X-ray crystallography. The isolated natural samples of both 5 and 6 are determined to be the TFA salts instead of the neutral forms. It took 16 steps (longest linear sequence) to divergently access both 5 and 6 following

  首次对映选择性全合成了 (-)-球脒 D ( 5 ) 和 (-)-异球脒 D ( 6 )。通过 X 射线晶体学明确阐明了它们的绝对构型。分离的天然样品5和6被确定为TFA盐而不是中性形式。遵循统一策略，需要 16 个步骤（最长的线性序列）才能分别访问第5 步和第 6 步。关键反应包括 (1) 开发和应用不对称 Meerwein-Eschenmoser-Claisen 重排来构建具有挑战性的 C10、C23 连续立体中心，以及 (2) 级联 6- exo -dig/6- exo -tet 胺/腈的应用环化反应。
