IBIETA JIMENEZ, Gabriela et al. Synthesis of the new 4-hydroxy-3-(3-methyl-2-butenyl)chalcone by microwave-assisted condensation of 4-hydroxy-3-(3-methyl-2-butenyl) acetophenone isolated from senecio graveolens and benzaldehyde. Rev. Bol. Quim [online]. 2017, vol.34, n.3, pp.89-103. ISSN 0250-5460.
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.
