The hydrocarbon trans-Ph·[C≡C] 2 ·CH=CHMe (tritium-labelled in the benzene ring) was inserted into the tuberous roots of two Dahlia hybrids and found to be converted into the ω-alcohol trans-Ph·[C≡C] 2 ·CH=CH·CH 2 ·OH, the threo-diol Ph·[C≡C] 2 · CH(OH)·CHMe·OH, and the threo-triol Ph·[C≡C] 2 ·CH(OH)·CH(OH)·CH 2 ·OH, but not into the hydrocarbon Ph·[C≡C] 3 ·Me. The diol and triol had not previously been recognised as natural products.
