A chlorinated dihydrobenzofuran from Flourensia riparia

Abstract

A new chlorinated compound, 5-acetyl-2,3-dihydro-2- (2-[1-chloro-2-hydroxypropyl])-benzofuran has been isolated from the chloroformic extract of the aerial parts of Flourensia riparia Griseb., along with the previously known benzofuran 2,3-dihydro-11,12-dihydroxyeuparin. Structural characterization was carried out by spectroscopic methods.

A partir del extracto clorofórmico de partes aéreas de Flourensia riparia Griseb., se identificó el nuevo compuesto clorado, 5-acetil-2,3-dihidro-2-(2-[1-cloro-2-hidroxipropil])-benzofurano (1) y 2,3-dihidro-11,12-dihidroxieuparina (2), un derivado previamente descripto. Las determinaciones estructurales se realizaron mediante métodos espectroscópicos.
