4-(Pyrrolidin-1-yl)pyridine-catalyzed deconjugative esterification of 2-cyclohexylideneacetic acids afforded isopropyl 2-(cyclohex-l-enyl)acetate by employing 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride as a coupling reagent. On the other hand, 4-(pyrrolidin-1-yl)pyridine-catalyzed esterification with 1,3-dicyclohexylcarbodiimide was not accompanied by deconjugation and gave isopropyl 2-cyclohexylideneacetate.

4-(Pyrrolidin-1-yl)pyridine-catalyzed carbodiimide couplings can produce isopropyl 2-(cyclohex-l-enyl)acetate from 2-cyclohexylideneacetic acids, offering a novel de
