title: Oxidative couplings on tryptophan-based diketopiperazines leading to fused and bridged chemotypes.
abstract: New chemotypes are obtained from tryptophan-containing diketopiperazines through selective C-C or C-N intramolecular oxidative couplings. The choice of the oxidant source dictates the outcome of the reaction.
