Abstract

Bis(oxazolines) are a well-known class of ligands in the area of asymmetric catalysis. Most of these ligands are C 2-symmetric due to the synthetic route employed for their synthesis. This review article summarizes the recent progress of the closely related, but relatively unexplored, C 1-symmetric bis(oxazoline) ligands and compares and contrasts the two where applicable.
