Abstract:
(EN) The invention relates to a method for obtaining taiwaniaquinoids having general formula (13), which can be used as synthesis intermediates in the production of other taiwaniaquinoids and derivatives. The method comprises the condensation between α-cyclocitral or β-cyclocitral and a halogenated derivative having formula (11) in order to obtain a compound having formula (12), which is subsequently cyclized and dehydrated by means of acid treatment to produce the tricyclic structure [6-5-6] of the taiwaniaquinoids.

El procedimiento comprende la condensación entre α-ciclocitral o β-ciclocitral y un derivado halogenado de fórmula (11), para obtener un compuesto de fórmula (12), que a continuación se cicla y deshidrata por tratamiento ácido para dar la estructura tricíclica [6-5-6] de los taiwaniaquinoides.
