Conjugate hydrosilylation of 3,3-diarylacrylate derivatives catalyzed by chiral rhodium-bis(oxazolinyl)phenyl complexes (1 mol %) at 60 degrees 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%.

Deoxycholic acid derived binaphthyl phosphites promote a highly enantioselective Rh‐catalyzed conjugate addition of arylboronic acids to 3‐arylpropenoates, giving useful chiral building blocks for the synthesis of biologically active compounds. The protocol was successfully applied to the enantioselective synthesis of the antimuscarinic drug (R)‐tolterodine.
