by the “umpoled” 1,4‐dioxygenation pattern characteristic for the polyketide frame of amphidinolide F was mastered by a late‐stage ring‐closing alkyne metathesis followed by a directed transannular hydration under the aegis of a carbophilic π‐acid catalyst. This concordant strategy enabled a concise total synthesis of this enticing marine natural product.
精心策划但又不和谐:由苯环环戊内酯F的聚酮化合物骨架的“缩略的” 1,4-双加氧模式特征所构成的挑战是由晚期闭环炔烃复分解,然后在嗜碳性物质的保护下进行定向的环过水合来解决的。 π-酸催化剂。这种协调一致的策略使这种诱人的海洋天然产物得以简明的合成。
