"The in situ hydrozirconation-transmetalation-aldehyde addition process is a convenient method for the generation of allylic alcohols. Ongoing research has focused on enhancing the enantioselectivity and substrate scope of this process. A chiral β-amino thiol scaffold was evaluated in the addition reaction. Amino thiols tend to provide the highest ee's, in part due to the higher affinity of sulfur for zinc over zirconium. A class of valine-based thiol ligands was identified to be effective for the formation of enantiomerically enriched allylic alcohols in terms of low ligand loading and high % ee. © 2007 Wiley-Liss, Inc."^^ .
