Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 112068-01-6, molcular formula is C17H19NO, introducing its new discovery. category: catalyst-ligand

Asymmetric aryl transfer of triphenylboroxin to a set of aryl aldehydes has been carried out in the presence of chiral amino alcohols derived from (S)-proline with high enantioselectivity. Substituted phenyl boroxins were also used as aryl source in asymmetric arylation of benzaldehyde.

The synthesis of a new class of bifunctional organophosphorus catalysts for the asymmetric borane reduction of prochiral ketones has been investigated. Keys to the architecture of effective catalysts are an oxazaphospholidine structural unit and a hydroxyaryl moiety. These (o-hydroxyaryl)oxazaphospholidine oxides have been successfully applied to the catalytic (2 mol-%) asymmetric borane reduction of numerous prochiral ketones with enantiomeric excesses up to 84% ee.
