The C1′–C11′ portion of the antibiotic pamamycin-607, a novel homologue and C2-epimer of nonactic acid, was synthesized in six steps from 4,5-hexadien-1-ol via a novel -selective oxymercuration/transpalladation/methoxycarboxylation of a γ-silyloxyallene and a -selective reduction of a 2-(2-tetrahydrofuranyl)acrylate using magnesium in methanol.
