Reduction of thioamides to amines


Recent Literature

4-Dimethylaminopyridine-BH3 as the boryl radical precursor promotes a desulfurizative reduction to access organic amines in the presence of PhSH as the polarity reversal catalyst. Alternatively a N-heterocyclic carbene-BH3 as the boryl radical precursor and sterically bulky Ph3CSH as catalyst can be used for annulation of unsaturated thioamides allowing for the construction of N-heterocyclic and carbocyclic skeletons.
