Allylsilane in synthesis: new syntheses of (±)-desepoxy-4,5-didehydromethylenomycin a and (±)-xanthocidin
Abstract
(±)-Desepoxy-4,5-didehydromethylenomycin A and (±)-xanthocidin were synthesised via a common β-silyl enone intermediate obtained from an efficient, highly regioselective oxidation of an allylsilane.
