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.
Copper-catalyzed diastereoselective arylation of tryptophan derivatives: Total synthesis of (+)-naseseazines A and B

A copper-catalyzed arylation of tryptophan derivatives is reported. The reaction proceeds with high site-and diastereoselectivity to provide aryl pyrroloindoline products in one step from simple starting materials. The utility of this transformation is highlighted in the five-step syntheses of the natural products (+)-naseseazine A and B.

The tryptophan (Trp) aromatic residue in chiral matrices often exhibits a large optical activity and thus provides valuable structural information. However, it can also obscure spectral contributions from other peptide parts. To better understand the indu
