Synthesis and Anti-Tuberculosis Activity of Substituted 3,4-(dicoumarin-3-yl)-2,5-diphenyl Furans and Pyrroles

open access: yesEngineering Proceedings, 2022
Increasing rates of multi-drug resistant (MDR) and extremely-drug resistant (XDR) cases of tuberculosis (TB) strains are alarming, and eventually hampered an effective control of the pathogenic disease. In the present study, nine derivatives of 2,3-bis(2-

Ready Access to Densely Substituted Furans Using TsujiWacker-Type Cyclization

open access: yes, 2021
A competent method for the construction of highly substituted furans catalyzed by Pd­(II) and Cu­(II) chloride has been developed. The method provides easy access to di-, tri-, and tetrasubstituted furans from corresponding diols with relatively mild ...

QSTR Models in Dioxins and Dioxin-like Compounds Provide Insights into Gene Expression Dysregulation

open access: yesToxics
Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzo-p-furans (PCDD/Fs) are a group of organic chemicals containing three-ring structures that can be substituted with one to eight chlorine atoms, leading to 75 dioxin and 135 furan congeners.

The photohydrolysis of furans

open access: yesScience
The defossilization of the chemical industry is accelerated by the shift from petroleum- to biomass-based feedstocks. At the center stage are bioderived furans, from which valuable platform chemicals can be obtained exclusively through oxidative or reductive processes.
