The chemical behavior of 4,9-dimethoxy-5-oxo-5H-furo[3,2-g]chromene-6-carbonitrile (1) was investigated toward some acyclic and cyclic active methylene ketones namely acetylacetone, ethyl acetoacetate, ethyl benzoylacetate, acetoacetanilide, dimedone, indanedione, pyrazolidine-3,5-dione and 5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one, barbituric acid and 1-allylthiobarbituric acid, and hippuric acid.

Design, Synthesis and Antifungal Activity of Benzofuran and Its Analogues

The Summary of main observation and conclusion Benzofuran has antifungal activity as the inhibitor of N-myristoyltransferase. Twenty-nine novel benzofuran-semicarbazide hybrids were designed and synthesized by principle of drug combinationatory. On this basis, the benzofuran ring was simplified to a resorcinol structure, and sixteen novel 1,3-dialkoxybenzene-semicarbazide hybrids were designed and synthesized. All structures of the target compounds were characterized by HRMS and NMR. The in vitro antifungal activity of target compounds was evaluated using the microdilution broth method against eight strains of pathogenic fungi with fluconazole as positive control. According to the results of the target compounds, structure-activity relationship (SAR) is summarized. The inhibitory activity against the tested strains of simplified compounds (K01-K16) has different levels improvement compared with compounds Z01-Z29. K01-K16 showed significant antifungal activities against A. fumigatus, C. kruseii, and sensitive C. albicans 5314. Notably, compounds Z20, Z22, K10, K11 and K16 also displayed different activities against two fluconazole-resistance strains that were isolated from AIDS patients. The minimal inhibitory concentration (MIC) values against fluconazole-resistant strains were in the range of 2-8 mu g/mL and 4-32 mu g/mL, respectively. Furthermore, molecular docking was performed to investigate the binding affinities and interaction modes between the target compound and N-myristoyltransferase.

Synthesis of sigma Receptor Ligands with a Spirocyclic System Connected with a Tetrahydroisoquinoline Moiety via Different Linkers

With the aim to develop new sigma(2) receptor ligands, spirocyclic piperidines or cyclohexanamines with 2-benzopyran and 2-benzofuran scaffolds were connected to the 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline moiety by variable linkers. In addition to flexible alkyl chains, linkers containing an amide as functional group were synthesized. The 2-benzopyran and 2-benzofuran scaffold of the spirocyclic compounds were synthesized from 2-bromobenzaldehyde. The amide linkers were constructed by acylation of amines with chloroacetyl chloride and subsequent nucleophilic substitution, the alkyl linkers were obtained by LiAlH4 reduction of the corresponding amides. For the development of sigma(2) receptor ligands, the spirocyclic 2-benzopyran scaffold is more favorable than the ring-contracted 2-benzofuran system. Compounds bearing an alkyl chain as linker generally show higher sigma affinity than acyl linkers containing an amide as functional group. A higher sigma(1) affinity for the cis-configured cyclohexanamines than for the trans-configured derivatives was found. The highest sigma(2) affinity was observed for cis-configured spiro[[2]benzopyran-1,1 ‘-cyclohexan]-4 ‘-amine connected to the tetrahydroisoquinoline system by an ethylene spacer (cis-31, K-i (sigma(2))=200 nM; the highest sigma(1) affinity was recorded for the corresponding 2-benzofuran derivative with a CH2C=O linker (cis-29, K-i (sigma(1))=129 nM).

Synthesis of Ni2P/Al2O3 utilizing triphenylphosphine (TPP) as the phosphorus source for hydrodeoxygenation of benzofuran

A novel route to synthesize highly active Ni2P/Al2O3 (TPP) utilizing triphenylphosphine (TPP) as the phosphorus source at a low temperature of 573 K is described. The as-prepared catalysts were characterized by X-ray diffraction (XRD), CO uptake, Brunner-Emmett-Teller (BET) measurements, and X-ray photoelectron spectroscopy (XPS). The catalytic activity of the Ni2P/Al2O3 (TPP) catalyst and the role of the TPP phosphorus source were studied using hydrodeoxygenation (HDO) of benzofuran (BF) as a probe reaction. The results show that the use of TPP as the phosphorus source could suppress the strong interaction between phosphate and Al2O3, thereby the formation of AlPO4 was avoided. As compared to the Ni2P/Al2O3 prepared by using (NH4)(2)HPO4 as the phosphorus source, Ni2P/Al2O3 (TPP) possessed significantly higher surface area and smaller Ni2P particle size. The HDO activity and yield of O-free products over the Ni2P/Al2O3 (TPP) catalyst were increased by 17.2% and 36.0%, respectively, when compared with those found for Ni2P/Al2O3 prepared using (NH4)(2)HPO4. The use of TPP as the phosphorus source could effectively promote the dehydration of 2-ethylphenol (2-EtPh) to form ethylbenzene (EB), and the demethylation of ethylcyclohexane (ECH) to methylcyclohexane (MCH).

Electrooxidation enables highly regioselective dearomative annulation of indole and benzofuran derivatives

The dearomatization of arenes represents a powerful synthetic methodology to provide three-dimensional chemicals of high added value. Here we report a general and practical protocol for regioselective dearomative annulation of indole and benzofuran derivatives in an electrochemical way. Under undivided electrolytic conditions, a series of highly functionalized five to eight-membered heterocycle-2,3-fused indolines and dihydrobenzofurans, which are typically unattainable under thermal conditions, can be successfully accessed in high yield with excellent regio- and stereo-selectivity. This transformation can also tolerate a wide range of functional groups and achieve good efficiency in large-scale synthesis under oxidant-free conditions. In addition, cyclic voltammetry, electron paramagnetic resonance (EPR) and kinetic studies indicate that the dehydrogenative dearomatization annulations arise from the anodic oxidation of indole into indole radical cation, and this process is the rate-determining step.

Chemoenzymatic Synthesis of (-)-Ribisins A and B from Dibenzo[b,d]furan

cis-Dihydrodiols, derived from monocyclic aromatic compounds, are valuable chiral pool intermediates for the synthesis of cyclic natural products. A drawback of this approach, to the synthesis of polycyclic secondary metabolites, is that additional rings must be annulated. To date, relatively few chiral natural products have been synthesized from polycyclic arene cis-dihydrodiols. Fungal metabolites, (-)-ribisins A and B, have now been obtained by functional group manipulation of a tricyclic arene metabolite, obtained from toluene dioxygenase-catalyzed regioselective and stereoselective cis-dihydroxylations of dibenzo[b,d]furan. The synthetic sequences were marginally shorter than the alternative routes, using monocyclic arene cis-dihydrodiols, and required no carbon-carbon bond-forming reactions.
