accomplish the totalsyntheses of tetrangulol, kanglemycinM, X-14881-E, and anhydrolandomycinone in moderate to good overall yields. The requisite diene was synthesized in excellent yield from a known enyne through an intramolecular enyne metathesis. The scope of this flexible and divergent strategy can be extended to the syntheses of similar scaffolds and unnatural aromatic angucyclinones.
