Copper(II) bromide and oxidant promoted 5‐endo‐dig and 5‐endo‐dig/6‐endo‐dig cascade reactions are presented. Substituted benzo[b]furans, indoles, and indeno[1,2‐c]chromenes bearing Sec‐peptides in position 3 were prepared. This procedure can be successfully applied for protected and unprotected peptides obtained in up to quantitative yields.
