Regioselective synthesis of fused ring heterocyclic derivatives of ketene aminals and their biological activities

A regioselective and convenient methodology was developed to synthesize heterocyclic derivatives, bearing imidazole, piperidines, and azepines rings. TheN-arylnitrones derived from 3-formylchromones were selected to react with heterocyclic ketene aminal to furnish the structurally attractive and pharmacologically important fused ring heterocycles. TheN-arylnitrone moiety of 3-formylchromone was used to activate the formyl group for regioselective fused ring heterocycles synthesis, whereas, the effect of substituents at aryl functionality of nitrones were studied to improve the yield of target fused ring heterocyclic products. The synthesized compounds(10-12)were evaluated for their in vitro cytotoxic and antifungal influences. In cytotoxic (brine shrimp lethality) assay, compound11ewas found to be active with LD50= 4.1 x 10(-6)mu g/mL.

Synthesis of substituted piperidines by enantioselective desymmetrizing intramolecular aza-Michael reactions

An organocatalytic enantioselective intramolecular aza-Michael reaction has been described for the first time in a desymmetrization process employing substrates different from cyclohexadienones. By using 9-amino-9-deoxy-epi-hydroquinine as the catalyst and trifluoroacetic acid as a co-catalyst, a series of enantiomerically enriched 2,5-and 2,6-disubstituted piperidines have been obtained in good yields and with moderate diastereoselectivity. Depending on the catalyst/co-catalyst loading ratio, either the major or the minor diastereoisomer of the final piperidine products was achieved with high levels of enantioselectivity. Finally, some mechanistic insights have been considered by means of theoretical calculations which were in agreement with the experimental results obtained in the desymmetrization reaction.

Cell-free in vitro reduction of carboxylates to aldehydes: With crude enzyme preparations to a key pharmaceutical building block

The scarcity of practical methods for aldehyde synthesis in chemistry necessitates the development of mild, selective procedures. Carboxylic acid reductases catalyze aldehyde formation from stable carboxylic acid precursors in an aqueous solution. Carboxylic acid reductases were employed to catalyze aldehyde formation in a cell-free system with activation energy and reducing equivalents provided through auxiliary proteins for ATP and NADPH recycling. In situ product removal was used to suppress over-reduction due to background enzyme activities, and an N-protected 4-formyl-piperidine pharma synthon was prepared in 61% isolated yield. This is the first report of preparative aldehyde synthesis with carboxylic acid reductases employing crude, commercially available enzyme preparations.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 10310-21-1 help many people in the next few years. SDS of cas: 10310-21-1.

Synthesis of Diastereomeric Pyrrolidine Sulfamides via Anchimerically Assisted Nucleophilic Substitution Reactions

The Mitsunobu reaction was employed in a key step during the development of a convenient synthetic route for the enantioselective preparation of pyrrolidine-sulfamide ligands from (R)-or (S)- [(S)-1-benzylpyrrolidin-2-yl](phenyl) methanol, and employing tert-butyl pyrrolidin-1-yl-sulfonylcarbamate as a non-conventional nucleophilic source. Although it is well documented that the exposure of this type of diastereomeric amino alcohols to the above-mentioned nucleophile usually leads to the formation of piperidines via ring expansion, either through classical nucleophilic substitution or the Mitsunobu version, only the pyrrolidine derivatives were generated with retention of configuration on the exocyclic stereocenter, owing to the neighboring group participation (internal backside nucleophilic substitution, S(N)ib). Final removal of the N-Boc protecting group from the sulfamide fragment afforded chiral compounds with significant potential as chiral ligands in asymmetric catalysis.

A simple method for the rapid synthesis of 2-amino-7,7-dimethyl-5-oxo-1,4-diaryl-hexahydroquinoline-3-carboxamide derivatives

Simple synthesis of oxoquinoline carboxamide derivatives via one-pot, multi-component reaction of enaminones derived from the addition of dimedone to various anilines with aromatic aldehydes and cyanoacetamide is described. Optimal reaction conditions for the synthesis of products were obtained, when EtOH/H2O (1:1) was used as the solvent at 80 degrees C, in the presence of piperidine as the catalyst. The reactions are completed within 5-25 min, in good to high yields (74-85%). This protocol involves Michael reaction, imine-enamine tautomerization, and cyclization sequences. The structures of products were deduced from their IR, mass, H-1 NMR, and C-13 NMR spectra. This method includes some important aspects including simple operation under mild conditions, easy accessibility of reactants, workup procedure, high atom economy, and the use of ethanol/water as a green media.

Access to Enantio-enriched Substituted alpha-Trifluoromethyl Azepanes from L-Proline

4-Substituted alpha-trifluoromethyl azepanes C were synthesized via the ring expansion of trifluoromethyl pyrrolidines A, which were synthesized from L-proline via a regioselective ring-opening of a bicyclic azetidinium intermediate B by various nucleophiles. The regioselectivity of the ring expansion is induced by the presence of a trifluoromethyl group. The chirality of the starting material was transferred to the azepanes with high enantiomeric excess.

Palladium-Catalyzed Synthesis of Amidines via tert-Butyl isocyanide Insertion

Para-substituted iodobenzenes were reacted withtent-butyl isocyanide and piperidine as nucleophiles in a the presence of palladium-diphosphine catalysts. Both single and double insertion of the isocyanide was observed and the corresponding amidines and ketimine-amidines were obtained in yields of practical interest. With the increase of the tert-butyl isocyanide/iodobenzene ratio, 100% chemoselectivity toward the ketimine-amidine was achieved. The formation of the products was rationalized on the basis of a catalytic cycle analogous to that of the aminocarbonylation reactions. Clear connection was found between the activity and the electronic structure of the proposed catalyst Pd(diphosphine) by computational studies, as the more negative partial charge on palladium resulted in higher conversion. Among five isocyanide substrates, only tert-butyl isocyanide was proved to be active.

2-Amino-5-(cyanomethylsulfanyl)-1H-pyrroles from Propargylamines, Isothiocyanates, and Bromoacetonitrile by One-Pot Synthetic Protocol

Tertiary propargylamines (such as N,N-dialkylpropargylamines, N-propargylpyrrolidine, -piperidine, and -morpholine), isothiocyanates, and bromoacetonitrile have been shown to be readily available building blocks for the highly selective one-pot construction of rare-functionalized pyrroles, namely so far inaccessible 1-substituted 2-amino-5-(cyanomethylsulfanyl)-1H-pyrroles, in up to 92 % yield. This highly efficient and operationally simple approach includes the initial formation of lithium but-2-ynimidothioate (adduct of monolithiated propargylamine and isothiocyanate), its transformation into potassium buta-2,3-dienimidothioate under the action of the t-BuOK/DMSO system (through acetylene-allene isomerization and the exchange by cations), intramolecular cyclization into potassium thienylamide (at <= 15 degrees C), followed by its re-cyclization into potassium pyrrolylsulfide at a higher temperature (45-60 degrees C), and the final S-alkylation of the latter with bromoacetonitrile.
