A proton NMR analysis of the OCH3 group conformation in 2‐methoxypyridines

The absence of HH couplings between the methoxy group and the ring protons observed in 2‐methoxy‐, 2,6‐dimethoxy‐ and 2‐methoxy‐6‐chloropyridines is interpreted in terms of a cis conformation between the methyl fragment and the nitrogen ring atom. Other data, taken from the current literature, supp...
