Actinopyrone A, an anti-Helicobacter pylori agent, was synthesized in nine steps from a silyl dienol ether. A vinylogous anti-aldol was stereoselectively synthesized by our developed remote stereoinduction methodology; coupling of this with a sulfone and a phosphonate species led to the construction of a vinylpyrone compound. This was submitted to reductive de-conjugation to give actinopyrone A. The absolute stereochemistry of actinopyrone A was determined to have the configuration 14R,15R.
