First total synthesis of antiostatin A1, a potent carbazole-based naturally occurring antioxidant, Chem. Commun., 2009, 1464 - 1466The first total synthesis of the potent antioxidant antiostatin A1 is reported, where its key features rely on a chemo- and regioselective rhodium-catalysed crossed alkyne cyclotrimerisation reaction applying functionalised ynamides and a palladium-catalysed arylamidation reaction.
