Transformation of secologanin and its ethylene acetal was investigated under acidic and basic conditions. Under acidic conditions both compounds gave benzaldehyde and an undefined fragment. A primary amine was incorporated into the substrate by lactamization with or without deglucosylation. Secondary and tertiary amines catalyzed lactonization of secologanin, but piperidine cleaved the acetal into
