The reaction of secologanin (1) (mainly in its tetraacetylated form 1a) with histamine (2) and its benzyl derivative (2b) was investigated. With the benzylated amine (2b), the main product was the normal, tetraacetylated benzyl derivative of histeloside having the R configuration at the new center of chirality, C-1 (5b), with a small amount of an unidentified minor component (probably the 1S epimer
