β-keto acids and vinyl azides are found to be promising precursors for the synthesis of pyrroles with Mn(acac)3 as a catalyst. One electron oxidation of β-keto acids by Mn(acac)3 induces decarboxylation to afford α-keto radicals, which then add on to vinyl azides, leading to the formation of iminyl...
