## Abstract The one‐bond ^13^C^13^C coupling constants (^1^__J__CC) in all nine possible dithieno[__b,d__]pyridines were measured at natural isotope abundance by using the INADEQUATE pulse sequence technique. The unambiguous assignments of the ^13^C NMR shifts of these compounds are also reported.

✦ Synopsis
Abstract
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.
