Acridanyl-substituted enamines, their iminium salts, and the corresponding ketones were obtained by reaction of the N-methylacridinium salts with the enamines in dimethyl sulfoxide at room temperature. The quinolinium and isoquinolinium salts have lower activities; the N-methylpyridinium cation does not react at all under the indicated conditions. \\\\expert2\\nbo\\Chemistry of Heterocyclic Compounds\\1979, v.15, N 5, p.541.pdf |
