A Rh(I)-catalyzed enantioselective silylation of aliphatic C-H bonds for the synthesis of Si-stereogenic dihydrobenzosiloles is demonstrated. This reaction involves a highly enantioselective intramol. C(sp3)-H silylation of dihydrosilanes, followed by a stereospecific intermol. alkene hydrosilylation leading to the asym. tetrasubstituted silanes. A wide range of dihydrosilanes and alkenes displaying various functional groups are compatible with this process, giving access to a variety of highly functionalized Si-stereogenic dihydrobenzosiloles in good to excellent yields and enantioselectivities.
