High‐field 2D NMR studies of mortonins were performed at 500 MHz ( 1 H) and 125 MHz ( 13 C). Unambiguous assignment both of the 13 C data to the carbon skeleton and that of the proton chemical shifts in these molecules was achieved, together with the establishment of the configuration of the asymmetric centres. Some previously reported signals have been reassigned.
