  AbstractIn boiling dilute sulphuric acid hydration of (±)‐trans‐chrysanthemic acid occurs to give the crystalline (±)‐trans‐δ‐hydroxydihydrochrysanthemic acid. In like manner (+)‐and (‐)‐trans‐chrysanthemic acids yield the crystalline (‐)‐ and (+)‐trans‐δ‐hydroxy‐dihydrochrysanthemic acids respectively. No racemization occurs as the recovered ( + )‐and ( ‐ )‐trans‐chrysanthemic acids have unchanged specific rotation.The lactonization of (±)‐cis‐chrysanthemic acid to (±)‐cis‐dihydrochrysanthemo‐δ‐lactone in boiling dilute sulphuric acid is shown to be reversible and to constitute an example of lacto‐enoic tautomerism. ( + )‐ and ( ‐ )‐cis‐Chrysanthemic acids are similarly lactonized to the crystalline (+)‐ and (‐)‐cis‐dihydrochrysanthemo‐δ‐lactones. The latter lactone is not identical with (‐)‐pyrocin, whose structure is confirmed as (‐)‐β‐isobutenyliso‐hexano‐γ‐lactone.
