The synthesis and absolute configuration of SCH 351448, an interesting ionophoric natural product, are reported herein. Mukaiyama aldol-Prins and segment-coupling Prins reactions were employed to construct the constituent tetrahydropyrans of SCH 351448. Efforts to assemble the C2-symmetric core of the natural product by a templated olefin metathesis strategy are described; however, a stepwise fragment
本文报道了 SCH 351448(一种有趣的离子载体天然产物)的合成和绝对构型。Mukaiyama aldol-Prins 和段偶联 Prins 反应被用来构建 SCH 351448 的组成四氢吡喃。描述了通过模板化烯烃复分解策略组装天然产物的 C2 对称核心的努力;然而,最终利用逐步片段组装来完成目标分子。
