An efficient and economical synthesis of the naturally occurring aromataseinhibitor abyssinone II was performed. The synthesis features an optimized aromatic prenylation reaction in which an arylcopper intermediate is reacted with prenyl bromide to afford a key intermediate that was converted to a prenylated aromatic aldehyde. Condensation of the aldehyde with an o-hydroxyacetophenone under Claisen-Schmidt

The present invention is related to a family of phenyl-prenyl derivatives of formula (I), and to their use in the treatment of cognitive, neurodegenerative or neuronal diseases or disorders, such as Alzheimer's disease or Parkinson's Disease. The present invention also relates to pharmaceutical compositions comprising the same. Further, the present invention is directed to the compounds of formula (I) for medical use, particularly for the use for the treatment and/or prevention of a cognitive, neurodegenerative or neuronal disease or disorder, and to the use of the compounds in the manufacture of a medicament for the treatment and/or prevention of a cognitive, neurodegenerative or neuronal disease or disorder.
