Biochemical characterization of two Brassica oleracea nitrile-specifier proteins [PDF]

Frontiers in Plant Science
Brassica oleracea vegetables (e. g. cabbages) form bioactive isothiocyanates (ITCs) from glucosinolate (GLS) hydrolysis. However, enzymatic activity, acidic pH (below pH 5), and ferrous ions (Fe2+) can promote nitrile release, reducing the ITC amount. In

B–N/B–H Transborylation: borane-catalysed nitrile hydroboration

Beilstein Journal of Organic Chemistry, 2022
The reduction of nitriles to primary amines is a useful transformation in organic synthesis, however, it often relies upon stoichiometric reagents or transition-metal catalysis.

Room Temperature Reduction of Titanium Tetrachloride-Activated Nitriles to Primary Amines with Ammonia-Borane

Molecules, 2022
The reduction of a variety of aromatic and aliphatic nitriles, activated by a molar equivalent of titanium tetrachloride, has been achieved at room temperature using ammonia borane as a safe reductant. The corresponding methanamines were isolated in good

A Proterozoic microbial origin of extant cyanide-hydrolyzing enzyme diversity

Frontiers in Microbiology, 2023
In addition to its role as a toxic environmental contaminant, cyanide has been hypothesized to play a key role in prebiotic chemistry and early biogeochemical evolution.
