## Abstract It is shown that dimethyl heptalene‐1,2‐dicarboxylates undergo rearrangements at temperatures > 200° to yield the corresponding 1,3‐dicarboxylates, which are isolated as the more stable 3,5‐dicarboxylates. ^2^H‐ and ^13^C‐labelling experiments with dimethyl 7‐isopropyl‐5,10‐dimethylhept
