The asymmetric induction is essentially identical for a range of substrates when the VAPOL and VANOL (see picture; but not 1,1′-binaphth-2-ol (BINOL)) ligands were employed in asymmetric aziridinations catalyzed by triphenylborate (90-98% ee). The synthetic utility of these catalysts is illustrated in a synthesis of L-3,4-dihydroxyphenyl-alanine (L-DOPA).
