Lecture 1: Key Concepts in Stereoselective Synthesis
... Olefins with no coordinating functionalities, especially tri- and tetrasubstituted, have been identified as the most difficult substrates for asymmetric hydrogenation. These olefins are particularly difficult to hydrogenate due to the absence of the polar group which is required for Rh or Ru catalys ...
