High chemoselectivity in the phenol synthesis
Beilstein Journal of Organic Chemistry, 2011 Efforts to trap early intermediates of the gold-catalyzed phenol synthesis failed. Neither inter- nor intramolecularly offered vinyl groups, ketones or alcohols were able to intercept the gold carbenoid species. This indicates that the competing steps of

Acta Crystallographica Section E: Crystallographic Communications, 2017 The title molecular salts, C15H20NO+·C4H3O4−, (I), and C9H15INO+·C4H3O4−, (II), have very similar molecular geometries for both cation and anion. The anions of both (I) and (II) are practically planar (r.m.s. deviations = 0.062 and 0.072 Å, respectively)

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

Gold(I)-catalyzed formation of furans by a Claisen-type rearrangement of ynenyl allyl ethers
Beilstein Journal of Organic Chemistry, 2011 A series of ynenyl allyl ethers were rearranged into polysubstituted furans in the presence of a gold(I) catalyst. It is proposed that the transformation involves a Claisen-type rearrangement that allows the efficient creation of quaternary centers under

Chemotaxis to Furan Compounds by Furan-Degrading Pseudomonas Strains [PDF]
Applied and Environmental Microbiology, 2012 ABSTRACT Two Pseudomonas strains known to utilize furan derivatives were shown to respond chemotactically to furfural, 5-hydroxymethylfurfural, furfuryl alcohol, and 2-furoic acid. In addition, a LysR-family regulatory protein known to regulate furan metabolic genes was found to be involved in regulating ...
