A rhodium(III)-catalyzed hydrosilylation/cyclization reaction of cyclohexadienone-tethered α,β-unsaturated aldehydes (1,6-dienes) with triethylsilane is described, providing a series of -hydrobenzofurans, -hydroindoles, and -hydroindenes bearing silyl enol ether in good to excellent yields and excellent stereoselectivities. Additionally, the versatility of this method was demonstrated through a gram-scale
