Treatment with ammonia, methylamine, n- propylamine, aniline, and p-toluidine furnished the 8-berberinylidene derivatives IV and VII- X. Reaction of V with malononitrile, ethyl acetoacetate, and ethyl malonate anions yielded the 8-berberinylidene derivatives XII-XIV. Acid hydrolysis of XIV gave 8-berberinylacetic ...
