A convergent and enantioselective synthesis of the C3-C19 bis-oxane oxazole fragment of phorboxazole B has been described. This work features highly efficient substrate-controlled reductions to construct the functionalised cis-oxane and a Mukaiyama aldol reaction followed by an intramolecular Williamson reaction leading to a trans-oxane.
已经描述了佛波唑 B 的 C3-C19 双恶烷恶唑片段的会聚和对映选择性合成。这项工作的特点是高效的底物控制还原来构建官能化的顺式氧杂环己烷和 Mukaiyama 羟醛反应,然后是分子内威廉姆森反应产生反式氧杂环己烷。
