| Research Abstract |
Chemistry of chiral silicon centers remain unexplored, when compared to that of chiral carbon centers, mainly due to the lack of methods for the construction of chiral silicon centers. The purpose of this study is to develop a catalytic method for the generation of chiral silicon centers on the basis of rhodium-catalyzed synthesis of benzosiloles, which we reported previously. We found that the substrate containing an isopropyldimethylsilyl group was employed, a less bulky methyl group is cleaved exclusively, and enantioselective cleavage of two enantiotopic methyl groups was possible by adding a chiral phosphine ligand to form a benzosilole bearing a chiral silicon center.
