Iron-mediated deuterium addition cascade cyano insertion/cyclization of -arylacrylamides to access deuterium-labelled phenanthridines
Deuterated molecules feature important biological activities and pharmacokinetic properties for the design of pharmaceuticals. Radical cyclization cascades involving the deuteration of alkenes to form heterocyclic compounds have rarely been reported. Herein, a deuterium addition cascade cyano insert...
