Abstract The formal syntheses of (±)-nephromopsinic acid,(−)-phaseolinic acid, and the first total synthesis of (−)-dihydropertusaric acid from (±)-and (−)-7-oxabicyclo [2.2. 1] hept-5-en-2- one are described. These syntheses take advantage of a previously reported radical rearrangement (1, 2-acyl migration). A remarkable iodide-mediated cleavage of a bicyclic system, followed by the introduction of the γ-chains via a mixed Kolbe electrolysis, are the ...
