BACKGROUND The aim of the current work was to determine thermo dynamical properties of 5(2-nitro phenyl)-furan-2-carbaldehyde, 5(3-nitro phenyl)-furan-2-carbaldehyde and 5(4-nitro phenyl)-furan-2-carbaldehyde. RESULTS The temperature dependence of saturated vapor pressure of 5(2-nitro phenyl)-furan-2-carbaldehyde, 5(3-nitro phenyl)-furan-2-carbaldehyde and 5(4-nitro phenyl)-furan-2-carbaldehy...

A furan amino acid, inspired by the recently discovered proximicin natural products, was incorporated into the scaffold of a DNA-binding hairpin polyamide. While unpaired oligomers of 2,4-disubstituted furan amino acids show poor DNA-binding activity, furan (Fn) carboxamides paired with N-methylpyrrole (Py) and N-methylimidazole (Im) rings demonstrate excellent stabilization of duplex DNA as we...

The aim of this work is to develop and discuss a lumped kinetic mechanism of furan, 2-methyl-furan, and 2,5-dimethylfuran to simulate the pyrolysis conditions, experimentally studied in shock tube and flow reactors and in a wide range of temperature and pressure. The comparisons between experimental data and model predictions support the validity of the lumped kinetic model, but also highlight ...

A new strategy for cyclopenta[b]furan synthesis mediated by hypervalent iodine(III) has been described. The approach employs diacetoxyiodobenzene-induced initial dehydrogenation to a putative trienone intermediate and triggered sequential cycloisomerization to form the cyclo-penta[b]furan targets.

5-Phenyl-furan-2-carboxylic acids have emerged as a new, promising class of antimycobacterial agents that the ability to interfere with iron homeostasis. Considering lack structural data on these compounds, we analyzed crystal fluorinated ester derivative 5-(4-nitrophenyl)furan-2-carboxylic acid, one most potent candidates in series. Here, describe preparation methyl 5-(2-fluoro-4-nitrophenyl)f...

INTRODUCTION In earlier studies"2 of the photosensitization of furan vapour by mercury(3P1) atoms, it has been reported that the principal photochemical process is a clecarbonylation which has a quantum yield of 04 at a pressure of furan of a few mm Hg. The C3 fragment which was simultaneously produced was found to consist of a mixture of cyclopropene and methylacetylene. At high conversions, s...

An analogue of thiamine having a furan ring in place of the thiazolium ring has been synthesised by a short and efficient route, involving gold(I)-catalysed cyclisation of an alkynyl alcohol to form the furan ring. The furan analogue of thiamine diphosphate (ThDP) was also made and tested for binding to and inhibition of pyruvate decarboxylase (PDC) from Zymomonas mobilis (overexpressed in E. c...

The title mol-ecule, C(18)H(20)O(3), is a furan-oid lignan extracted from the leaves of Larrea tridentata. The relative absolute configuration for the four chiral centers was established, showing that this compound is 4-epi-larreatricin, which has been previously reported in the literature. The mol-ecule displays noncrystallographic C(2) symmetry, with the methyl and phenol substituents alterna...

Synthesis of phenanthro[1,2-b]furan-10,11-dione, the core nucleus present in Tanshinone-I is described in 8-10 steps starting from 2-bromo-3,4-dihydro-1-naphthaldehyde. The bromoaldehyde was converted to methyl 2-(2-bromo-1-naphthyl)acetate or 2-(2-bromo-1-naphthyl)acetonitrile following the protocol of functional group transformations. Subsequent Suzuki coupling of this ester/nitrile derivativ...
