“In this way, we obtain a series of vicinal diamines that were previously difficult to produce. In doing so, we can precisely control the sites where the functional groups are located,” explains first author Dr. Guangying Tan. To this end, the chemists developed a class of special nitrogen radical precursors that simultaneously generate two nitrogen-centered radicals with different reactivities via an energy transfer process. By “regioselectively” adding two of these radicals stepwise via carbon-carbon double bonds, the scientists produce the unsymmetrically constructed vicinal diamines. “Regioselective” means that the reaction occurs at defined sites on the molecules.
“Methods for the efficient and controlled introduction of these heteroatoms into artificially produced, biologically active structures are therefore of great importance,” Frank Glorius emphasizes. “This also applies to the vicinal diamines we are focusing on.”
