“…Chromanes and benzofurans are characteristic metabolites of certain tribes of the Asteraceae family [1]. They are frequently found in several widely distributed American genera such as Senecio, Ageratina, Liatris, Encelia, Eupatorium, Baccharis, Verbesina and Flourensia, and have aroused great interest because of their numerous biological activities such as antimicrobial, allergenic, plant growth inhibitory, pro-apoptotic, and anti-proliferative against cancer cell lines [2].…”

“…Previous investigations on X. poposum (under the old Werneria poposa label) reported the presence of (-)kaur-16-en-19-al from petrol extract, 4-hydroxy-3-(isopenten-2-yl)-acetophenone (1) and 4-hydroxy-3-(3  -hydroxyisopentyl)-acetophenone from the methylene chloride extract [6a], and the coumarins aesculetin, fraxetin, isoscopoletin, and dihydroisoscopoletin along with the flavonoid isorhamnetein from the methanol extract (ME) [6b]. Recently, the phytotoxic activities of the benzofuran (2R)-6-hydroxytremetone (2) isolated from this plant have been reported [7].…”

The essential oil and methanol extract of northwestern Argentina medicinal plant Xenophyllum poposum, collected in Catamarca province, were investigated. GC and GC-MS analyses of the essential oil identified 56 compounds accounting for 92.9%. The main components of the oil were -cadinene (16.5%), 6-hydroxytremetone (14.7%), epi--cadinol (12.0%), -cadinol (8.8%), -cadinene (7.5%), 1-epi-cubenol (4.2%) and -muurolene (3.0%). The essential oil exhibited antibacterial activities against five pathogenic strains as well as antifungal activities against two pathogenic fungi. The methanol extract showed antibacterial activity against two strains of Staphylococcus aureus and two pathogenic fungal strains. The main components isolated from the methanol extract were the antifungal 4-hydroxy-3-(isopenten-2-yl)-acetophenone, 6-hydroxytremetone, and tremetone. 6-Hydroxytremetone showed activity against all the fungal strains and one of the S. aureus strains assayed. Antioxidant and radical-scavenging properties of the methanol extract and essential oil were determined using the 2,2'-diphenyl-1-picrylhydrazyl assay and β-carotene bleaching (BCB) test. The methanol extract and the essential oil showed, respectively, moderate and weak antioxidant activity when compared to butylated hydroxytoluene.

Copper Pincer Complexes as Advantageous Catalysts for the Heteroannulation of ortho‐Halophenols and Alkynes

2014

View full text Add to dashboard Cite

A new, non-symmetrical copper(II) pincer complex catalyzes much more efficiently the formation of benzofuran by the reaction between ortho-iodophenols and alkynes. The lowest catalyst loadings are realized for this reaction, and bromo-and chlorophenols are heteroannulated for the first time. Strong evidence for hydrophenoxylation and intra-molecular halogen atom-transfer steps catalyzed by this remarkably active, recyclable homogeneous catalyst is provided.
