摘要

The effect of periodic acid on oxidation of the quinoline alkaloids bucharaine, foliosidine, evoxine, and dubinidine was studied as a function of their structures and the reaction conditions. Periodic acid in dilute aqueous solutions was shown to form stable gem-diols. The use of a large excess of HIO₄ formed gem-diols and aldehydes. O-Methyl derivatives were obtained in aqueous MeOH solutions.
