Enantioselective Synthesis of alpha-(Hetero)aryl Piperidines through Asymmetric Hydrogenation of Pyridinium Salts and Its Mechanistic Insights

Enantioselective synthesis of alpha-aryl and alpha-heteroaryl piperidines is reported. The key step is an iridium-catalyzed asymmetric hydrogenation of substituted N-benzylpyridinium salts. High levels of enantioselectivity up to 99.3:0.7 er were obtained for a range of alpha-heteroaryl piperidines. DFT calculations support an outersphere dissociative mechanism for the pyridinium reduction. Notably, initial protonation of the final enamine intermediate determines the stereochemical outcome of the transformation rather than hydride reduction of the resultant iminium intermediate.

Proteomic and metabolic profile analysis of low-temperature storage responses inIpomoea batataLam. tuberous roots

Background Sweetpotato (Ipomoea batatasL.) is one of the seven major food crops grown worldwide. Cold stress often can cause protein expression pattern and substance contents variations for tuberous roots of sweetpotato during low-temperature storage. Recently, we developed proteometabolic profiles of the fresh sweetpotatoes (cv. Xinxiang) in an attempt to discern the cold stress-responsive mechanism of tuberous root crops during post-harvest storage. Results For roots stored under 4 degrees C condition, the CI index, REC and MDA content in roots were significantly higher than them at control temperature (13 degrees C). The activities of SOD, CAT, APX, O(2)(.-)producing rate, proline and especially soluble sugar contents were also significantly increased. Most of the differentially expressed proteins (DEPs) were implicated in pathways related to metabolic pathway, especially phenylpropanoids and followed by starch and sucrose metabolism. L-ascorbate peroxidase 3 and catalase were down-regulated during low temperature storage. alpha-amylase, sucrose synthase and fructokinase were significantly up-regulated in starch and sucrose metabolism, while beta-glucosidase, glucose-1-phosphate adenylyl-transferase and starch synthase were opposite. Furthermore, metabolome profiling revealed that glucosinolate biosynthesis, tropane, piperidine and pyridine alkaloid biosynthesis as well as protein digestion and absorption played a leading role in metabolic pathways of roots. Leucine, tryptophan, tyrosine, isoleucine and valine were all significantly up-regulated in glucosinolate biosynthesis. Conclusions Our proteomic and metabolic profile analysis of sweetpotatoes stored at low temperature reveal that the antioxidant enzymes activities, proline and especially soluble sugar content were significantly increased. Most of the DEPs were implicated in phenylpropanoids and followed by starch and sucrose metabolism. The discrepancy between proteomic (L-ascorbate peroxidase 3 and catalase) and biochemical (CAT/APX activity) data may be explained by higher H(2)O(2)levels and increased ascorbate redox states, which enhanced the CAT/APX activity indirectly. Glucosinolate biosynthesis played a leading role in metabolic pathways. Leucine, tryptophan, tyrosine, isoleucine and valine were all significantly up-regulated in glucosinolate biosynthesis.

One-Pot Tandem Hiyama Alkynylation/Cyclizations by Palladium(II) Acyclic Diaminocarbene (ADC) Complexes Yielding Biologically Relevant Benzofuran Scaffolds

A series of palladium acyclic diaminocarbene (ADC) complexes of the type cis-[((RNH)-N-1)(R-2)methylidene]-PdCl2(CNR1) [R-1 = 2,4,6-(CH3)(3)C6H2: R-2 = NC5H10 (2); NC4H8 (3); NC4H8O (4)] were used not only to perform the C-sp(2)-C-sp Hiyama coupling between aryl iodide and triethoxysilylalkynes but also to subsequently carry out the one-pot tandem Hiyama alkynylation/cyclization reaction between 2-iodophenol and triethoxysilylalkynes, giving a convenient time-efficient access to the biologically relevant benzofuran compounds. The palladium ADC complexes (2-4) were conveniently synthesized by the nucleophilic addition of secondary amines, namely, piperidine, pyrrolidine, and morpholine on the cis-{(2,4,6-(CH3)(3)C6H2)NC}(2)PdCl2 in moderate yields (ca. 61-66%).

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 622-26-4 help many people in the next few years. HPLC of Formula: C7H15NO.

Enantioselective Pd(II)-Catalyzed Intramolecular Oxidative 6-endo Aminoacetoxylation of Unactivated Alkenes

A novel asymmetric 6-endo aminoacetoxylation of unactivated alkenes by palladium catalysis, which yields chiral beta-acetoxylated piperidines with excellent chemo-, regio- and enantioselectivities under very mild reaction conditions, has been established herein by employing a new designed pyridine-oxazoline (Pyox) ligand. Importantly, introducing a sterically bulky group into the C-6 position of Pyox is crucial to enhance the reactivity of the aminoacetoxylation of alkenes.

Synthesis and antibacterial evaluation of new sulfanyltetrazole derivatives bearing piperidine dithiocarbamate moiety

A series of new alkyl or aryl sulfanyltetrazole derivatives containing dithiocarbamate moiety (5a-6e) were synthesized. The structures of the compounds were characterized by IR, H-1 NMR, C-13 NMR spectra, and elemental analysis data. The present study examines the antibacterial potential of novel synthetic sulfanyltetrazole compounds against clinically important gram-positive and -negative strains. The results of screening showed that attachment of dithiocarbamate to sulfanyltetrazole derivatives results in enhancement of antibacterial activity. The compound 6d showed the best activity among the tested compounds. Also, the less polar 2,5-disubstituted sulfanyltetrazole regioisomers showed an increased antibacterial activity compared with the corresponding more polar regioisomers. [GRAPHICS] .

Fluorinated piperidine iminosugars and their N-alkylated derivatives: Synthesis, conformational analysis, immunosuppressive and glycosidase inhibitory activity studies

The fluorinated piperidine iminosugars 2a-4a and their N-octyl and N-decyl derivatives 2b,c-4b,c were synthesized from D-mannoseio-xylose using nucleophilic fluorination as the key step. The conformation of iminosugars 2/3, either C-2(5) or C-5(2), was assigned based on the H-1 NMR studies at different pH. immunomodulatory activity of 2a,c-4a,c was examined using Mixed Lymphocyte Reaction (MLR) and B-cell assay. The N-alkylated fluorinated D-manno-iminosugars 3b/4b were found to be better immunosuppressive agents (IC50=5-6 mu M) on T-cells. The fluorinated iminosugar 3a/4a act as potent and selective inhibitors of beta-glucosidase (IC50= 4-8 mu M). The N-alkyl-iminosugars 4b-c were found to be moderate inhibitors of alpha-glucosidase (yeast) and a-galactosidase (coffee beans), respectively. (C) 2018 Elsevier Ltd. All rights reserved.
