Tandem cyclisation of vinyl radicals: a sustainable approach to indolines utilizing visible-light photoredox catalysis
2,3-Disubstituted indoles can be efficiently synthesised at room temperature from readily available benzylated ortho-amino-α-bromocinnamates by a photoredox catalysed tandem radical 1,6-H-translocation-cyclisation strategy, advancing previous protocols that called for overstoichiometric use of Bu3SnH/AIBN and reflux temperatures.
