Abstract: Methyl 5,6-Bis(2-methoxyphenyl)-1,4-dimethyl-7-oxobicyclo[2.2.1] hept-5-en-2-endo-carboxylate, a moderately crowded norbornenone ester, exhibits complex VT-DNMR behav iour. A similar behaviour is not seen in its 7-oxa analogue, showing that conformational transmission from position 7 has a crucial influence on the distance parameters that govern the dynamic processes involving the substituents on the bicycloheptene framework.
