Significance

Optically active propargyl alcohols remain an important target in synthesis. While work by many groups has shown success in addition of alkynes to aldehydes, some of the reported procedures work only for aliphatic aldehydes due to problems with the Cannizzaro reaction for aromatic aldehydes. The Pedro group has shown previous success with the readily available mandelamide-type ligands and optimization led to the use of 1 as the best ligand for this reaction.
