We report a selective, mild, and efficient C-H functionalization of tryptophan and tryptophan-containing peptides with activated α-bromo-carbonyl compounds under visible-light irradiation. The protocol efficiency is outlined by the wide substrate scope and excellent tolerance of sensitive functional groups present in the amino acid side chains. The method can be successfully extended to access pharmaco-peptide conjugate scaffolds.

, p. 1001 - 1013 (2007/10/03)
A convenient high yield and general method is described for the synthesis of difengpin (8a) and aryl cinnamates (8b-h and 9a,b) from benzaldehydes (7a-h)
