The synthesis features a base-catalyzed alkynyl silane alcoholysis/ring-closing enyne metathesis sequence for facile construction of a 1,3-diene motif. A diene RCM followed by a ring-contractive allylic transposition of cyclic silyl ethers was incorporated for the stereoselective installation of a functionalized 1,5-diene subunit. An efficient proline-mediated direct cross-aldol condensation of two
完成了 (-)-amphidinolide V 的不对称全合成。该合成具有碱催化的炔基硅烷醇解/闭环烯炔复分解序列,可轻松构建 1,3-二烯基序。引入二烯 RCM,然后是环状甲硅烷基醚的缩环烯丙基转座,用于立体选择性安装功能化的 1,5-二烯亚单元。两种高级醛中间体的高效脯氨酸介导的直接交叉羟醛缩合被用于构建关键的 α,β-不饱和环氧醛。这种全合成证明了金属催化转化在复杂分子合成中的威力。
