Conjugate hydrosilylation of 3,3-diarylacrylate derivatives catalyzed by chiral rhodium-bis(oxazolinyl)phenyl complexes (1 mol %) at 60 °C for 2 h was investigated to prepare optically active 3,3-diarylpropanoate derivatives in high yields up to 99% yield and high enantioselectivities up to 99%.

Asymmetric β-Boration of α,β-Unsaturated Carbonyl Compounds with Chiral Rh[bis(oxazolinyl)phenyl] Catalysts. -Chiral rhodium[bis(oxazolinyl)phenyl] complexes exhibit high catalytic activity for the enantioselective β-boration of α,β-unsaturated esters, ketones, and amides. Cyclic enones, lactones, and β,β-disubstituted acrylates do not react under the given conditions. -(TORIBATAKE, K.; ZHOU, L.; TSURUTA, A.; NISHIYAMA*, H.; Tetrahedron 69 (2013) 17, 3551-3560, http://dx.

Enantioselective Synthesis of Optically Active 3,3-Diarylpropanoates by Conjugate Hydrosilylation with Chiral Rh-Bis(oxazolinyl)phenyl Catalysts. -RHC efficiently promotes the asymmetric hydrosilylation of 3,3-diarylacrylates. After acidic work-up diarylpropanoates are obtained in high optical purity. -(ITOH, K.; TSURUTA, A.; ITO, J.-I.; YAMAMOTO, Y.; NISHIYAMA*, H.; J. Org.
