Reactions of phenols having a methylene-tethered chiral allenylsilane at the para position with a hypervalent iodine reagent result in chirality-transferring oxidative intramolecular cyclization accompanied by dearomatization of the phenol to stereoselectively give spiro[4.5]decadienones possessing a silylethynyl group.
