摘要/Abstract

描述了一种四丁基溴化铵介导的环化芳香化反应用于β-咔啉的合成,反应物使用容易得到的色氨酸和N-甲基苯胺.这种不使用金属催化剂的策略是现存β-咔啉合成方法的有益补充.

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
