Plant coumarins: VII. Amination of oreoselone trifluoromethanesulfonate

Amination of oreoselone trifluoromethanesulfonate with N-substituted piperazines, anabasine, aniline derivatives, quinolin- and isoquinolinamines, and amino acids of the penicillin and cephalosporin series in the presence of palladium complexes gave the corresponding N-substituted 3-aminofurocoumarins. The yield of the amination products depended on the catalytic system and base used.
