A mild and efficient nBu4NBr-mediated oxidative cycloaromatization to prepare β-carbolines from readily available tryptophans and N-methylaniline is described. The present metal free protocol is complementary to the existing methods for the synthesis of aromatic β-carbolines.

Key words: β-carboline, tetra-n-butylammonium bromide, N-methylaniline, cycloaromatization
