In the original article I have presented the stereochemical structures of ApppD, ApppI, and AppD. Stereochemical structures of the adenosine part of the compounds are “upside down”, and the real stereochemical structures are presented here for Figures 2 and 3. Also the solvent used in the synthesis of ApppD has been presented incorrectly in the original article in Scheme 1; it is NOT acetonitrile (CH3CN) but dimethylformamide (DMF).
