Metal-Free-Visible Light C-H Alkylation of Heteroaromatics via Hypervalent Iodine-Promoted Decarboxylation

A metal-free photoredox C-H alkylation of heteroaromatics from readily available carboxylic acids using an organic photocatalyst and hypervalent iodine reagents under blue LED light is reported. The developed methodology tolerates a broad range of functional groups and can be applied to the late-stage functionalization of drugs and drug-like molecules. The reaction mechanism was investigated with control experiments and photophysical experiments as well as DFT calculations.

New asymmetrical per-substituted cyclodextrins (2-O-methyl-3-O-ethyl- and 2-O-ethyl-3-O-methyl-6-O-t-butyldimethylsilyl-beta-derivatives) as chiral selectors for enantioselective gas chromatography in the flavour and fragrance field

Asymmetrically substituted 6I-VII-O-t-butyldimethylsilyl(TBDMS)-3I-VII-O-ethyl-2I-VII-O-methyl-beta-cyclodextrin (MeEt-CD) and 6I-VII-O-TBDMS-2I-VII-O-ethyl-3I-VII-O-methyl-beta-cyclodextrin (EtMe-CD) were synthesised to evaluate the role of the substitution pattern in positions 2 and 3 on the enantioselectivity, in particular in view of their application to routine analysis in fast enantioselective gas chromatography (Es-GC). The chromatographic properties and enantioselectivities of the new derivatives were tested by separating the enantiomers of a series of medium-to-high volatility racemates in the flavour and fragrance field, and compared to those of the corresponding symmetrically substituted 6I-VII-O-TBDMS-2I-VII,3I-VII-O-methyl-beta-CD (MeMe-CD) and 6I-VII-O-TBDMS-2I-VII,3I-VII-O-ethyl-beta-CD (EtEt-CD), and were then applied to analysis of real-world essential oil (e.o.) samples. A new synthetic process including the sonochemical approach to obtain synthetic reproducibility and significant yields of the per-substituted derivatives with acceptable reaction times was developed. The results show that asymmetrically substituted methyl/ethyl CDs compared to the methyl or ethyl symmetrical derivatives in general provide better enantioselectivity in terms of both enantiomer resolution and number of separated chiral compounds, and show how the substitution pattern in positions 2 and 3 of the CD ring can influence the separation. Moreover, these new CD derivatives with better enantioselectivity are also shown to be very useful in routine analysis for the exhaustive control of samples containing several chiral characterizing markers in a single run.

Construction of perhydro indol-2-ones by a methoxide catalyzed deacetylation-Michael-aldol cascade

An efficient, stereoselective Michael-aldol cascade for the one-pot construction of the perhydro indol-2-one bicyclic ring system using an acetate protected doubly-activated pyrrole-2-one pro-nucleophile and alpha,beta-unsaturated carbonyl compounds has been developed. Initiated by a methoxide deacetylation in methanol at room temperature, the cascade is easy to perform, stereoselective, efficient and broad in scope to this synthetically relevant structure.

Fenbufen, a new anti inflammatory analgesic: synthesis and structure activity relationships of analogs

100 analogs of fenbufen were prepared and tested using the carrageenan, polyarthritis, and UV erythema anti inflammatory tests and the 2 phenyl 1,4 benzoquinone writhing and inflamed paw pressure analgesic tests. Only 3 retained the same full spectrum of activity as fenbufen: dl 4 (4 biphenylyl) 4 hydroxybutyric acid, dl 4 (4 biphenylyl) 1,4 butanediol, and 4 biphenylacetic acid. Fenbufen had the same spectrum of activity as aspirin, phenylbutazone, and indomethacin in the 5 tests. In addition, dose response derived potencies show fenbufen more potent than aspirin and at least as potent as phenylbutazone in all 5 tests. Two related compounds were generally similar.

Novel selective PDE4 inhibitors. 1. Synthesis, structure-activity relationships, and molecular modeling of 4-(3,4-dimethoxyphenyl)-2H-phthalazin-1-ones and analogues

A number of 6-(3,4-dimethoxyphenyl)-4,5-dihydro-2H-pyridazin-3-ones and a novel series of 4-(3,4-dimethoxyphenyl)-2H-phthalazin-1-ones were prepared and tested on the cGMP-inhibited phosphodiesterase (PDE3) and cAMP-specific phosphodiesterase (PDE4) enzymes. All tested compounds were found to specifically inhibit PDE4 except for pyridazinone 3b, which showed moderate PDE4 (pIC50 = 6.5) as well as PDE3 (pIC50 = 6.6) inhibitory activity. In both the pyridazinone and phthlazinone series it was found that N-substitution is beneficial for PDE4 inhibition, whereas in the pyridazinone series it also accounts for PDE4 selectivity. In the phthalazinone series, the cis-4a,5,6,7,8,8a-hexahydrophthalazinones and their corresponding 4a,5,8,8a-tetrahydro analogues showed potent PDE4 inhibitory potency (10/11c,d: pIC50 = 7.6-8.4). A molecular modeling study revealed that the cis-fused cyclohexa(e)ne rings occupy a region in space different from that occupied by the other fused (un)saturated hydrocarbon rings applied; we therefore assume that the steric interactions of these rings with the binding site play an important role in enzyme inhibition.

Difluorocyclobutylacetylenes as positive allosteric modulators of mGluR5 with reduced bioactivation potential

Schizophrenia is a serious illness that affects millions of patients and has been associated with N-methyl-D-aspartate receptor (NMDAR) hypofunction. It has been demonstrated that activation of metabotropic glutamate receptor 5 (mGluR5) enhances NMDA receptor function, suggesting the potential utility of mGluR5 positive allosteric modulators (PAMs) in the treatment of schizophrenia. Herein we describe the optimization of an mGluR5 PAM by replacement of a phenyl with aliphatic heterocycles and carbocycles as a strategy to reduce bioactivation in a biaryl acetylene chemotype. Replacement with a difluorocyclobutane followed by further optimization culminated in the identification of compound 32, a low fold shift PAM with reduced bioactivation potential. Compound 32 demonstrated favorable brain uptake and robust efficacy in mouse novel object recognition (NOR) at low doses.

Characterization of Secondary Metabolites from Various Solvent Extracts of Saffron Floral Waste

Isolation of secondary metabolites from saffron flower waste (stamens), and their identification using chromatographic techniques was carried out. Extraction was carried out with solvents (methanol, ethanol, ethyl acetate, diethylether and hexane) with different polarity. Gas chromatography?mass spectroscopy (GC?MS) technique was used for identification and structure elucidation of secondary metabolites obtained from saffron flower stamens. Chromatogram of ethanol showed higher peak area as compared to other solvents. Ethanol extract showed maximum number of peaks while chromatogram of hexane extract showed minimum number of peaks indicating that polarity of the solvent plays an important role in the extraction process. GC?MS analysis confirmed presence of many important compounds in saffron stamens such as alpha-tocopherol or vitamin E, dibutyl para-cresol, hydroquinone, and certain esters.
