The main oxygen compounds identified were phenols, diphenols, alkanones, furans and benzofurans
, while phenols constituted 7-8 wt% of oil (< 350 [degrees]C).
Recently, we reported a unique behavior of hydrazine hydrate towards certain benzofurans
to produce phenolic-based pyrazoles .
derivative compounds, this typical class was not well known for the genus Dalbergia ; however, the naturally occurring benzofurans
119-124 were available in D.
The two first compounds provided by SIRIUS/ CSI:MSFinger for formula C13H12O4 shared benzofuran
structure (13, 15, UNPD); few hundred benzofurans
have been identified in all morphological parts of plants, mainly belonging to Asteraceae family .
Liu, Design, Synthesis and Structure-Activity Relationship of Novel Oxime Ether Strobilurin Derivatives Containing Substituted Benzofurans
. Pest Manag.
Based on the survey of recent literature studies on coumarins and benzofurans
and in our effort to discover novel antimicrobial [13-16] and anticancer agents [17,18], the aim of our work is synthesis of 4-(3-hydroxy-benzofuran-2yl)coumarins and the evaluation of them for their therapeutic importance.
But in spite of this, incineration also presents environmental risks (dioxins and benzofurans
) and is limited by the high costs of handling, transport and elimination of the final contaminated material [2-13].
NMR spectral data of benzofurans
and bithiophenes from hairy root cultures of Tagetes patula and the molecular structure of isoeuparin.
Within each skeletal group, compounds are ordered into hydrocarbons, acids, aldehydes, ketones, alcohols, esters, ethers, chlorinated compounds, benzofurans
, benzopyrans, and nitrogen-containing compounds.
Similar results have been reported in response to a number of preemergence herbicide families including the benzofurans
, and diamino-s-triazines (Harper, 1982; Callahan, 1994) and the dinitroanilines (Seagle, 1978; Finney, 1991; Callahan, 1994).
Smits, Three- Step Synthesis of an Array of Substituted Benzofurans
Using Polymer-Supported Reagents, J.
The main oxygen-containing compounds identified are phenols, diphenols, 2-, 3- and 4-alkanones, furans and benzofurans
. Among the oxygen compounds, phenols constitute 7-8 wt% of oil (<350 [degrees]C), the next most abundant being ketones.
