An efficient synthesis of [6]-paradol (1) has been performed in four steps with a 72.0% overall yield. The present method highlights commercially available materials, convenient isolation with multiple crystallization without involving column chromatography, and a high-purity product (more than 99.2%), and it is amenable to large-scale synthesis.
t-5-en-4-one (1) and 4-[3-hydroxydecyl]-2-methoxyphenol (2), isolated from the dried seeds of Grains of Paradise (Aframomum melegueta), were synthesized; the latter compound was made as the S-enantiomer and the material derived from the seeds was found to be a 1:1.7 mixture of the R and S isomers. The synthetic route used should allow the preparation of analogs having extended alkyl chains and consequently
The present application generally relates to the use of metabolites of ginger and analogs thereof for the treatment and prevention of diseases, including but not limited to, cancer.
