Studies on antihyperlipidemic agents. I. Synthesis and hypolipidemic activities of phenoxyphenyl alkanoic acid derivatives

The alkanoic acids containing phenoxyphenyl moiety at omega-position were prepared and tested for hypolipidemic property. Some of the compounds showed hypoglycemic activity besides hypolipolipidemic one. Further study on the selected compound, 3-[4-(4-chlorophenoxy)benzoyl]propionic acid (8) revealed that it increased insulin sensitivity of adipose tissue of obese and diabetic mice (KKA(y)). The structure-activity relationship was discussed briefly.

Efficient synthesis of spirolactones from cyclic anhydrides via an allylation/alkylation-RCM sequence

Starting from cyclic anhydrides the diallyl or dibutenyl lactones were obtained. The ring closing metathesis reaction of these using the Grubbs catalyst provided the corresponding spirolactones in good yields. With diallyl delta-lactone 2h, RCM occurred only in the presence of titanium tetraisopropoxide.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: Tetrahydrofurans, you can also check out more blogs about4100-80-5

An efficient synthesis of low-covered polyrotaxanes grafted with poly(epsilon-caprolactone) and the mechanical properties of its cross-linked elastomers

Advanced polyrotaxane elastomers were fabricated by the synthesis of poly(epsilon-caprolactone)-grafted polyrotaxanes with significantly lower coverage than previously achieved. The time course for the complexation of alpha-cyclodextrin with an end-functionalized polyethylene glycol (PEG) was analyzed by subsequent end-capping and polyrotaxane isolation, which revealed that the bulkiness of the PEG end group affects the time required for complex nucleation and the resulting coverage. Low-coverage poly(epsilon-caprolactone)-grafted polyrotaxanes were synthesized in a facile and large-scale manner by optimizing the simultaneous hydrolysis of the end-capping groups and the solubility of the product during the ring-opening polymerization of epsilon-caprolactone. Cross-linking the thermoplastic graft polyrotaxanes yielded elastomers that are much more extensible than conventional elastomers with fivefold higher coverages. Elastomers with lower coverages behave as ideal elastic bodies due to chain sliding through the cross-links, which suggests that the arrangement entropy of the cyclic components, which counteracts chain sliding, is substantially decreased by reduced coverage.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4100-80-5 is helpful to your research. Reference of 4100-80-5

Synthesis of ABE tricyclic analogues of methyllycaconitine using a Wacker oxidation-aldol strategy to append the B ring to the AE fragment

The synthesis of ABE tricyclic analogues 18 of the alkaloid methyllycaconitine 1 is described. The analogues contain the key pharmacophore reputed to be responsible for the biological activity of methyllycaconitine 1, namely, a homocholine motif formed from a tertiary N-ethylamine in a 3-azabicyclo[3.3.1]nonane ring system and a 2-(3-methyl-2,5-dioxopyrrolin-1-yl)benzoate ester side chain. The 3-azabicyclo[3.3.1]nonane ring system 10 was assembled via a double Mannich reaction of ethyl 3-(but-3? -enyl)-2-oxocyclohexane-1-carboxylate 9 with ethylamine and formaldehyde. Attempts to append a B ring to this AE ring system via McMurray coupling of dialdehyde 5 were hampered by the inability to effect conversion of the C-9 ketone 10 to vinyl ether 6. Wittig methylenation of ketone 10 afforded diene 7, however, subsequent attempts to effect double hydroboration-oxidation of diene 7 failed to realise diol 11 en route to the key dialdehyde precursor 5 required for the McMurray coupling. Wacker oxidation of the homoallyl group of 10 afforded methyl ketone 12 which underwent intramolecular aldol condensation to form enone 13. After selective reduction of the ketone and methylation, the resultant methyl ethers 15 underwent reduction of the ester sidechain affording neopentyl substituted alcohols 16. Finally, the 2-(3-methyl-2,5-dioxopyrrolin-1-yl)benzoate ester sidechain was appended by treatment of alcohols 16 with N-(trifluoroacetyl)anthranilic acid followed by fusion of the resultant anthranilates 17 with methylsuccinic anhydride.

Ketosantalic Acid, a New Sesquiterpenic Acid from Indian Sandalwood Oil

Indian sandalwood oil contains over one hundred constituents including about fifteen acids, some occuring only in traces.One of these is a new acid (11-keto-dihydro-alpha-santalic acid, 8), isolated as its methyl ester (9).Its structure has been determined on the basis of spectral and chemical evidences, including its conversion into the gamma-lactone (10) and the nitrogen-containing compound (12), formed via reduction with sodium borohydride and Wolff-Kishner reaction respectively.Products obtained by Beckmann rearrangement of the oxime (34) and Wagner-Meerwein/Nametkin rearrangement of 9 also provide supporting evidences. 9 is resistant to Baeyer-Villiger oxidation.Certain synthetic approaches yield bi-?-tricyclyl (30), teresantalol (26) and an unsaturated alcohol (29).Oxidation of alpha-santalyl acetate (37) with t-butyl chromate, instead of yielding the desired 11-keto-alpha-santalyl acetate (38), gives 12-acetoxy-13-keto-nor-alpha-santalane (40), formation of which has been rationalised.

Vinegar metabolomics: An explorative study of commercial balsamic vinegars using gas chromatography-mass spectrometry

Balsamic vinegar is a popular food condiment produced from cooked grape must by two successive fermentation (anaerobic and aerobic) processes. Although many studies have been performed to determine the composition of major metabolites, including sugars and aroma compounds, no study has been undertaken yet to characterize the comprehensive metabolite composition of balsamic vinegars. Here, we present the first metabolomics study of commercial balsamic vinegars by gas chromatography coupled to mass spectrometry (GC-MS). The combination of three GC-MS methods allowed us to detect >1500 features in vinegar samples, of which 123 metabolites were accurately identified, including 25 amino acids, 26 carboxylic acids, 13 sugars and sugar alcohols, four fatty acids, one vitamin, one tripeptide and over 47 aroma compounds. Moreover, we identified for the first time in vinegar five volatile metabolites: acetin, 2-methylpyrazine, 2-acetyl-1-pyroline, 4-anisidine and 1,3-diacetoxypropane. Therefore, we demonstrated the capability of metabolomics for detecting and identifying large number of metabolites and some of them could be used to distinguish vinegar samples based on their origin and potentially quality.

Methyllycaconitine analogues have mixed antagonist effects at nicotinic acetylcholine receptors

Bicyclic analogues of methyllycaconitine (MLA), such as 12, have been synthesised that incorporate the C1-OMe substituent present in the natural product. Electrophysiology experiments using Xenopus oocytes expressing nicotinic acetylcholine receptors (nAChRs) were conducted on these analogues and a related tricyclic analogue 2. The most potent compound, 2, was an antagonist at all receptors studied but displayed different antagonist effects at each receptor subtype. This study more clearly defines the biological effects of MLA analogues at nAChRs and demonstrates that these analogues are not selective ligands for the alpha7 nAChR subtype.

Selectivity of Radical Formation in the Reaction of Carbonyl Compounds with Manganese(III) Acetate

The selectivity of radical generation in the oxidation of carbonyl compounds by manganese(III) has been studied in two ways.Competitive reaction of acetic and propionic acids under conditions in which the resultant radicals are trapped efficiently by an alkene suggests that propionic acid reacts some 3.8 times more readily than does acetic acid.Oxidation of butanone under similar conditions gives products in the formation of which reaction has occurred 2.9 times more readily at C-3 of butanone than at C-1.However, this ratio reflects a combination of chain propagation and of initiation by manganese(III) oxidation.When propagation is effectively eliminated, the C-1 position is the more reactive.The significance of these observations on the mechanism of oxidation of carbonyl compounds by manganese(III) is discussed.It is suggested that enol radical-cations can be formed in the reaction but that these do not give carbonyl-stabilised radicals by deprotonation.
