Summary

1. The Koenigs-Knorr condensation of acetobromorhamnose with strophanthidin acetate has given strophanthidin L-rhamnoside substituted at the C5 hydroxyl, and its condensation with free strophanthidin has given strophanthidin di-α-O-rhamnoside substituted at the C3 and C5 hydroxy groups.

2. Under similar conditions, methyl 2,3,4-tri-O-acetyl-l-bromo-1-deoxy-α-D-galacturonate and strophanthidin have given the corresponding strophanthidin diglycoside substituted at the C3 and C5 hydroxyls.
