It is slightly toxic to humans, on account of its tendency to react in the human body and produce reactive species of nitrogen and oxygen, which can damage internal structures. Direct reduction of substituted ketones bearing Lewis basic heteroatoms generally provided secondary alcohols of only modest enantiomeric excess likely due to either competition between the target carbonyl and the functionalized sidechains at the Lewis acidic boron atom in TarB-NO2 or the added steric bulk of the α-sidechain.
