Skipping out: The title reaction using internal secondary allylic phosphates proceeded with excellent γ regioselectivity and E stereoselectivity to give skipped enynes. Enantioenriched secondary allylic phosphates proceeded with 1,3-anti stereochemistry to afford the corresponding chiral 1,4-enynes, which were used for various derivatizations and the formal total synthesis of a GnRH antagonist. phen=1,10-phenanthroline.
