Synthetic disproof of the structure proposed for solanacol, the germination stimulant for seeds of root parasitic weeds

The structure proposed for solanacol, the germination stimulant for seeds of root parasitic weeds isolated from tobacco (Nicotiana tabacum L.), was synthesized. Comparison of the 1H NMR data of the synthetic compounds with those reported for solanacol showed the previously proposed structure to be incorrect.
