## Abstract The Ketonic ^13^C NMR signals of a series of 6‐hydroxy‐5‐oxobicyclo[2.2.2]oct‐7‐ene‐2‐carboxylic acid lactones and of haplophytine and related __N__‐substituted 3‐piperidinones occur at exceptionally high field; the structural factors which are responsible have been elucidated by compar
