Abstract
En el presente artículo reportamos la síntesis de una nueva chalcona, 4'-hidroxi-3'-(3-metil-2-butenil)chalcona 2, vía condensación orgánica asistida por irradiación de microondas de benzaldehído y 4-hidroxi-3-(3-metil-2-butenil)acetofenona 1, aislada de la especie vegetal Senecio graveolens. El compuesto 2, que es de origen sintético, no se ha aislado hasta ahora de fuentes naturales. Las estructuras fueron establecidas por técnicas modernas de RMN.
In this article we report the synthesis of a new chalcone, 4'-hydroxy-3'-(3-methyl-2-butenyl)chalcone 2, from the organic condensation assisted by microwave irradiation of benzaldehyde and 4-hydroxy-3-(3-methyl-2-butenyl)acetophenone 1, the latter isolated from Senecio graveolens. Compound 2, being of synthetic origin has not been so far isolated from natural sources. Structures were established by modern NMR techniques.
