Egonol. Spectrometric properties and derivatives

Egonol, a 2-phenylbenzofuranoid compound of known structure, was obtained from the seed oil of Styrax americana Lam. The nuclear magnetic resonance spectra of egonol and 3-nitroegonol were examined, and all of the proton signals were assigned. Egonoic acid and egonyl chloroacetate were prepared; their ultraviolet, infrared, and nuclear magnetic resonance spectra confirmed the structure of egonol. The content of egonol in oils may be estimated from the intensity of specified bands in the spectra.
