Reductive Amination Routes in the Synthesis of Piperidine IminoSugars

The reductive amination (RA) reaction plays a pivotal role in the synthesis of new C-N bonds, due to the availability of many different and low-cost reagents and their operational simplicity. The introduction in a compound of a nitrogen-containing moiety that can be reduced to an amine in the reaction medium allows to perform cascade reactions which further expand this method. The application of the intramolecular version of the RA to carbohydrates allows the synthesis of polyhydroxypiperidine iminosugars, which are among the most challenging and fascinating glycomimetics for a synthetic chemist. This minireview focuses on the use of RA and of the double reductive amination (DRA) reaction in the key ring-closing step en route to the synthesis of these compounds.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 13925-03-6, you can contact me at any time and look forward to more communication. Quality Control of 2-Ethyl-6-methylpyrazine.

Novel 2-cyanoacrylamido-4,5,6,7-tetrahydrobenzo[b]thiophene derivatives as potent anticancer agents

Ethyl 2-acrylamido-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate as well as its correspondingbis-derivatives,5-10, with aliphatic linkers were synthesized, fully characterized, and tested as novel anticancer agents. The targeted compounds,5-10, were obtained by the Knoevenagel condensation reactions ofbis-o- or -p-aldehyde with a molar ratio of ethyl 2-(2-cyanoacetamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate of2in the presence of piperidine in excellent yields (93-98%). The in vitro anticancer activities of the prepared compounds were evaluated against HepG2, MCF-7, HCT-116, and BJ1 cells. Compounds7and9emerged as the most promising compounds, with IC(50)values of 13.5 and 32.2 mu g/ml, respectively, against HepG2 cells, compared with the reference drug doxorubicin (IC50: 21.6 mu g/ml). Real-time reverse-transcription polymerase chain reaction was used to measure the changes in expression levels of the COL10A1 and COL11A1, ESR1, and ERBB2, or AXIN1 and CDKN2A genes within the treated cells, as genetic markers for colon, breast, or liver cancers, respectively. Treatment of the colon cancer cells with compounds5,9, and10, or breast and liver cancers cells with compounds7,8,9, and10downregulated the expression of the investigated tumor markers. The DNA damage values (depending on comet and DNA fragmentation assays) increased significantly upon treatment of colon cancer cells with compounds5,9, and10, and breast and liver cells with compounds8,9, and10. The structure-activity relationship suggested that the increase of the chain of the alkyl linker increases the anticancer activity and the compounds withbis-cyanoacrylamide moieties are more active than those with one cyanoacrylamide moiety.

Efficient Method for the Concentration Determination of Fmoc Groups Incorporated in the Core-Shell Materials by Fmoc-Glycine

In this paper, we described the synthesis procedure of TiO2@SiO(2)core-shell modified with 3-(aminopropyl)trimethoxysilane (APTMS). The chemical attachment of Fmoc-glycine (Fmoc-Gly-OH) at the surface of the core-shell structure was performed to determine the amount of active amino groups on the basis of the amount of Fmoc group calculation. We characterized nanostructures using various methods: transmission electron microscope (TEM), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and X-ray photoelectron spectroscopy (XPS) to confirm the modification effectiveness. The ultraviolet-visible spectroscopy (UV-vis) measurement was adopted for the quantitative determination of amino groups present on the TiO2@SiO(2)core-shell surface by determination of Fmoc substitution. The nanomaterials were functionalized by Fmoc-Gly-OH and then the fluorenylmethyloxycarbonyl (Fmoc) group was cleaved using 20% (v/v) solution of piperidine in DMF. This reaction led to the formation of a dibenzofulvene-piperidine adduct enabling the estimation of free Fmoc groups by measurement the maximum absorption at 289 and 301 nm using UV-vis spectroscopy. The calculations of Fmoc loading on core-shell materials was performed using different molar absorption coefficient: 5800 and 6089 dm(3)x mol(-1)x cm(-1)for lambda = 289 nm and both 7800 and 8021 dm(3)x mol(-1)x cm(-1)for lambda = 301 nm. The obtained results indicate that amount of Fmoc groups present on TiO2@SiO2-(CH2)(3)-NH(2)was calculated at 6 to 9 mu mol/g. Furthermore, all measurements were compared with Fmoc-Gly-OH used as the model sample.

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 13925-03-6 help many people in the next few years. Recommanded Product: 13925-03-6.

Synthesis of tetrafluorinated piperidines from nitrones via a visible-light-promoted annelation reaction

A method for the one-step construction of 3,3,4,4-tetrafluorinated piperidines from nitrones and readily accessible tetrafluorinated iodobromobutane is described. The reaction requires an excess amount of ascorbic acid as the terminal reductant and is performed in the presence of an iridium photocatalyst activated by blue light. The annelation is a result of a radical addition at the nitrone, intramolecular nucleophilic substitution, and reduction of the N-O bond.

Hexafluoroisopropanol-Promoted Haloamidation and Halolactonization of Unactivated Alkenes

Pyrrolidine and piperidine derivatives bearing halide functional groups are prevalent building blocks in drug discovery as halides can serve as an anchor for post-modifications. In principle, one of the simplest ways to build these frameworks is the haloamination of alkenes. While progress has been made in this field, notably with the development of enantioselective versions, this reaction is still fraught with limitations in terms of reactivity. Besides, a major question remaining is to understand the mechanism at work. The formation of a haliranium intermediate is typically mentioned, but limited mechanistic evidence supports it. Reported here is an efficient metal- and oxidant-free protocol to achieve the haloamidation of olefins, promoted by hexafluoroisopropanol, along with a DFT investigation of the mechanism. These findings should guide the future development of more complex transformations in the field of halofunctionalization.

Genetic Relationships among Different Chemotypes of Lupinus sulphureus

Lupines (Lupinus spp.) are a common plant legume species found on western U.S. rangelands. Lupinus spp. may contain quinolizidine and/or piperidine alkaloids that can be toxic and/or teratogenic to grazing livestock. Alkaloid profiles may vary between and within a species. The objectives of this study were to (1) further explore the characteristic alkaloid profiles of Lupinus sulphureus using field collections and (2) explore the phylogenetic relationship of the different populations and chemotypes of L. sulphureus using the amplified fragment length polymorphism method of DNA fingerprinting, thus providing possible explanations to the phenomena of multiple chemotypes within a species. A total of 49 accessions of L. sulphureus were classified into seven chemotypes. The DNA profiles showed that one L. sulphureus chemotype, chemotype A, is genetically divergent from the other chemotypes of L. sulphureus, suggesting that it represents an unresolved lupine taxon, possibly a new lupine species. Additionally, the different chemotypes of L. sulphureus represented different genetic groups, as shown by Bayesian cluster analysis and principle component analysis.

Anticancer Activity of Spirocyclic Hydroxamic Acids (Derivatives of 1-Hydroxy-1,4,8-Triazaspiro[4,5]Decan-2-One), Histone Deacetylase Inhibitors

Ten racemic spirocyclic hydroxamic acids (CHA 1-10, 1-hydroxy-1,4,8-triazaspiro [4,5]decan-2-one derivatives) containing pharmacophore imidazolidine and piperidine fragments with various substituents were synthesized. It was shown that CHA (1-10) are inhibitors of the activity of the histone deacetylase enzyme in cultured breast cancer cells. The study of antitumor activity in vivo CHA (1-10) showed that in polychemotherapy with cisplatin and cyclophosphamide these compounds possess pronounced chemosensitizing antitumor activity and increase the life span of experimental animals. Thus, it is shown that spirocyclic hydroxamic acids possess therapeutic potential in polychemotherapy for the treatment of oncological diseases.
