Rh-catalyzed enantioselective hydrosilylation of unactivated alkenes.

Here, we report a highly efficient rhodium-catalysed enantioselective hydrosilylation of unactivated alkenes, achieving excellent regioselectivity and high enantioselectivity. The use of a commercially available chiral ferrocene-based phosphine-oxazoline ligand was crucial in achieving excellent chiral induction and high reactivity with undirected unactiviated alkenes, delivering Si-stereogenic monohydrosilanes in high yields and excellent enantioselectivities. This protocol represents a robust, scalable method for the enantioselective synthesis of Si-stereogenic monohydrosilanes, featuring a low catalyst loading, a broad substrate scope and exceptional functional group and heterocycle tolerance. Moreover, the late-stage functionalization of complex motifs opens a new avenue for incorporating chiral silicon motifs into pharmaceuticals and bioactive compounds.
