Rh-catalyzed enantioselective spiroannulation of 2-alkenylphenols with alkynes was developed. In the presence of 5 mol% BINOL-derived (BINOL: 1,1'-bi-2,2'-naphthol) cyclopentadiene-Rh complex [(R)-CpRh1] and 2 equiv. of Cu(O- Ac)2, the C—H activation/annulation reaction proceeded smoothly to afford a wide range of enantioenriched spirocyclohexenones in up to 84% yield and 81% ee. This reaction features mild reaction conditions and good functional group tolerance.

Key words: 2‑alkenylphenol, alkyne, cyclopentadiene-Rh complex, spiroannulation, spirocyclohexenone
