Three natural strictosidine/vincoside-class glucoindole alkaloids have been chemically correlated with strictosidinic acid possessing a rigorously established stereostructure. The C-3 stereochemistry of palicoside, dolichantoside, and isodolichantoside has been firmly proved to be (S), (S), and (R), respectively.
