Description	Similar magnitudes of proton–proton couplings across three, four, and five bonds and proton–carbon couplings across two and three bonds combined with difficult to predict substituent effects make the results of an indiscriminate use of routine techniques for substitution sitedetermination in C-monosubstituted five-memberedheteroaromatics suspect. As demonstrated on two examples of natural products, the use of 1,1-ADEQUATE leads to unambiguous substitution site determination lending thus further support to suggested inclusion of 1,1-ADEQUATE data into computer-assisted structure elucidation (CASE) protocols.
