An ecofriendly, efficient method for the synthesis of new pharmacologically active 6-arylphenanthridines has been developed for the first time. This method involves consecutive microwave-assisted Suzuki–Miyaura and Pictet–Spengler processes starting from inexpensive available 2-bromoaniline derivatives and 3,4-dimethoxyphenylboronic acid to be easily converted into 2-aminobiphenyl precursors, which
