two‐directional Marshall propargylation strategy, whereas the highly adorned acid subunit 41 derives from D‐glutamic acid by an intramolecular oxa‐Michael addition and a proline‐mediated hydroxyacetone aldol reaction as the key steps; the necessary Me3Sn‐group on the terminus of 41 for use in the Stille coupling was installed via enol triflate 39, which was obtained by selective deprotonation/triflation

by the “umpoled” 1,4‐dioxygenation pattern characteristic for the polyketide frame of amphidinolideF 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 totalsynthesis of this enticing marine natural product.
