Azide Radical Initiated Ring Opening of Cyclopropenes Leading to Alkenyl Nitriles and Polycyclic Aromatic Compounds

Jérôme Waser, Bastian Antoine Rodolphe Claude Muriel

We report herein a radical‐mediated amination of cyclopropenes. The transformation proceeds through a cleavage of the three‐membered ring after the addition of an azide radical on the strained double bond and leads to tetrasubstituted alkenyl nitrile deriv ...

Divergent Asymmetric Synthesis of Polycyclic Compounds via Vinyl Triazenes

Rosario Scopelliti, Kay Severin, Nicolai Cramer, Gregor Kiefer, Abdusalom Suleymanov, Florian Gérald Abela, David Kossler

Vinyl triazenes were obtained by enantioselective [2+2] cycloaddition reactions of bicyclic alkenes with 1-alkynyl triazenes in the presence of a RuII catalyst with a chiral cyclopentadienyl ligand. These triazenes serve as unique vinyl cation surrogates. ...
