The reaction product is a mixture of isomers with preference for the endo isomer: Diels-Alder reaction of furan with arynes provides corresponding derivatives of dihydronaphthalenes, which are useful intermediates in synthesis of other polycyclic aromatic compounds. [16]
Formation of furan resin from furfuryl alcohol. Components produced by sand casting. Furan resins serve as binders for the casting moulds. Furan resin refers to polymers produced from various furan compounds, [1] of which the most common starting materials are furfuryl alcohol and furfural. In the resin and in the cured polyfurfurol, the furan ...
Furan fatty acids are reactive compounds. They are easily oxidizable by photooxidation , [ 10 ] autoxidation , [ 10 ] [ 11 ] [ 12 ] or catalyzed by lipoxygenase -1. [ 10 ] [ 13 ] [ 14 ] Upon the exposure to light, the aroma 3-methyl-2,4-nonanedione (MND) is formed from furan fatty acids in the reaction with singlet oxygen , which has a hay-like ...
In chemistry, a reactivity series (or reactivity series of elements) is an empirical, calculated, and structurally analytical progression [1] ...
Tetrabromobenzene can react with butyllithium and furan to form a tetrahydroanthracene [28] diaryne reaction with furan [4+2] cycloadditions of arynes have been commonly applied to natural product total synthesis. The main limitation of such approach, however, is the need to use constrained dienes, such as furan and cyclopentadiene. [14]
2,3-Dihydrofurans are intermediates in the Feist–Benary synthesis of furans from α-halogen ketones and β-dicarbonyl compounds. [4]The 2,3-dihydrofuran ring can be synthesized by several methods.
Benzofuran is the heterocyclic compound consisting of fused benzene and furan rings. This colourless liquid is a component of coal tar. Benzofuran is the structural nucleus (parent compound) of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants.
2,5-Furandicarboxylic acid (FDCA) is an organic chemical compound consisting of two carboxylic acid groups attached to a central furan ring. It was first reported as dehydromucic acid by Rudolph Fittig and Heinzelmann in 1876, who produced it via the action of concentrated hydrobromic acid upon mucic acid. [2]
