Abstract
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 cis-hydrobenzofurans,cis-hydroindoles,and cis-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 experiment and various downstream transformations,highlighting its utility.
