✦ Synopsis

In the first Corrigendum published from Schmidt et al., [1] it was revealed that the data published in footnote [25] of the original Communication [2] was that of an unidentified byproduct, and not that of alcohol 3. It is now clear that the data in footnote [28] is also incorrect, and does not pertain to the glycoside 10 b. The incorrect assignment resulted from the same type of error as for 3. The editorial office thanks Dr. Prasanna Jayalath and Dr. Ming Li from the laboratory of Professor David Crich for the preparation of authentic samples of 3 and 10 b [3] and for bringing this matter to our attention.
