Synthesis and biological evaluation of new benzofuran carboxamide derivatives

Journal of Saudi Chemical Society, 2017
A series of new 3-(glycinamido)-benzofuran-2-carboxamide and 3-(β-alanamido)-benzofuran-2-carboxamide derivatives (5a–o) were synthesized for the purpose of developing the new bioactive chemical entities and evaluated for their in vitro antimicrobial ...

Benzofuran derivatives. Part 3 On the reactivities of the intermediates in benzofuran synthesis

Journal of Heterocyclic Chemistry, 1987
Abstract3‐Methyl‐5‐nitrobenzofuran (2) and 3‐methyl‐5‐nitrobenzofuran‐2‐carboxylic acid (3) were obtained by heating 2‐acetyl‐4‐nitrophenoxyacetic acid (1) with various bases in acetic anhydride. It appeared that 3‐hydroxy‐3‐methyl‐5‐nitro‐2,3‐dihydrobenzofuran‐2‐carboxylic acid (4) was the intermediate in the benzofuran synthesis.

Bioactive Benzofuran derivatives: A review

European Journal of Medicinal Chemistry, 2015
In nature's collection of biologically active heterocycles, benzofuran derivatives constitute a major group. The broad spectrum of pharmacological activity in individual benzofurans indicates that this series of compounds is of an undoubted interest.

Benzofuran based PDE4 inhibitors

Bioorganic & Medicinal Chemistry, 1999
Replacement of the 3,4-dialkoxyphenyl substructure common to a number of PDE4 inhibitors with a 2-alkyl-7-methoxybenzofuran unit is described. This substitution can result in either enhancement or substantial reductions in PDE4 inhibitory activity depending on the system to which it is applied.

Benzofurans, benzofuran dimers and other constituents from Ophryosporus charua

Phytochemistry, 1997
Aerial parts of Ophryosporus charua afforded several known and five new benzofuran derivatives, as well as two prenylated p-hydroxyacetophenone derivatives. The essential oil contained lavandulyl acetate, lavandulol and dehydrotremetone as the main constituents.

Benzofuran Trimers for Organic Electroluminescence

Chemistry – A European Journal, 2004
AbstractFour linear benzofuran trimers have been prepared by a two‐stage synthetic procedure. They were tested as materials for organic electroluminescence (OEL). Precursor phenylene ethynylene oligomers were formed in the first stage, then after removal of the phenolic hydroxyl protecting groups, a base was used to promote the cyclization of ortho ...

Benzofuran bioisosteres of hallucinogenic tryptamines

Journal of Medicinal Chemistry, 1992
The benzofuran analogues of the hallucinogens 5-methoxy-N,N-dimethyltryptamine and 5-methoxy-alpha-methyltryptamine were synthesized and evaluated for affinity at the serotonin 5-HT2 and 5-HT1A receptors in rat brain homogenate, labeled with [125I]-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane ([125I]DOI) and [3H]-8-hydroxy-2-(N,N-di-n-propylamino ...

Catalytic transformations of benzofuran

Chemistry of Heterocyclic Compounds, 1974
When benzofuran is alkylated with tert-butyl chloride in the vapor phase (190–260‡C) in a flow system, the ratio of the 2- and 3-tert-butylbenzofurans formed varies from 2∶1 to 20∶1, depending on the acidity of the catalyst used (ZnCl2/Al2O3), because of conversion of the 3-isomer to the 2-isomer.

Reactivity of Benzofuran Derivatives

Synthetic Communications, 2014
Abstract This review presents a systematic and comprehensive survey of the chemical reactivity of benzofurans. These compounds are important intermediates for the synthesis of a variety of useful and novel heterocyclic systems that are otherwise difficult to obtain synthetically.
