Inspired by Barton's landmark total synthesis of Usnic acid, a method was devised by Baran for the direct oxidative coupling of indoles and pyrroles to a range of carbonyl compounds (Baran et al., J. Am. Chem. Soc. 2007, 129, 12857-69).
When one examines the piece of work to which such a description has been applied, it often contains only a minor improvement on a well-known reaction or a new application of an old technique.
