| Outline of Final Research Achievements |
Recently, catalytic asymmetric constructions of chiral silicon centers have been of great interest considering their unique chemical and physical properties. In this context, we demonstrated Rh-catalyzed enantioselective desymmetrizing intramolecular hydrosilylation of symmetrically disubstituted hydrosilanes. The original axially chiral phenanthroline ligand was found to work as an effective chiral catalyst for this transformation. A chiral silicon-stereogenic center is one of the chiral motifs gaining much attention in asymmetric syntheses and the present protocol provides cyclic five-membered organosilanes with a chiral silicon center with high enantioselectivity. Next, we are interested in application of Ir-catalyzed direct C-H silylation to the construction of chiral silicon center. Also for this transformation, the chiral phenanthrolines worked as effective ligands to give the desired products with moderate enantioselectivity.
