Abstract

The C-1-C-17 fragment of amphidinolides C, C2, C3, and F has been constructed from a trans-2,5-disubstituted dihydrofuranone prepared by diastereoselective rearrangement of a free or metal-bound oxonium ylide generated from a metal carbenoid. The dihydrofuranone was converted into an aldehyde corresponding to the C-1-C-8 framework, and this was coupled to the C-9-C-17 unit by nucleophilic addition of a vinylic anion
