Synthesis of (-)-Cytisine Using a 6-endo aza-Michael Addition

An asymmetric synthesis of (-)-cytisine has been achieved. The piperidine C-ring was formed using a stereodivergent intramolecular 6-endo aza-Michael addition. The B-ring was established by intramolecular pyridine N-alkylation. The absolute stereochemistry was established by an Evans acyl oxazolidinone enolate alkylation reaction that proceeded with an unexpected stereochemical outcome due to participation of the pyridine nitrogen lone pair.

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%).

Synthesis and evaluation of 4 ‘,5 ‘-dihydrospiro[piperidine-4,7 ‘-thieno [2,3-c]pyran] analogues against both active and dormant Mycobacterium tuberculosis

Need for new drugs to fight against tuberculosis (TB) is increasing day by day. In the present work we have taken a spiro compound (GSK 2200150A) reported by GSK as a lead and we modified the structure of the lead to study the antitubercular activity. For structure activity profiling twenty-one molecules have been synthesized, characterized and evaluated for their antimycobacterial potency against both active and dormant TB. Compound 06, 1-((4-methoxyphenyl) sulfonyl)-4′,5′-dihydrospiro[piperidine-4,7’-thieno[2,3-c]pyran] was found to be the most potent compound (MIC: 8.23 mu M) in active TB and was less effective than the lead but more potent than standard first line drug ethambutol. It was also found to be more efficacious than Isoniazid and Rifampicin and equipotent as Moxifloxacin against dormant Mycobacterium tuberculosis (MTB). Compound 06 also showed good inhibitory potential against over expressed latent MTB enzyme lysine epsilon-amino transferase with an IC50 of 1.04 +/- 0.32 mu M. This compound is a good candidate for drug development owing to potential against both active and dormant stages of MTB. (C) 2017 Elsevier Ltd. All rights reserved.

Synthesis of novel 2,5-substituted p-aminophenols and 2,5-substituted p-quinones in a one-pot reaction between alpha- alkoxyvinyl(ethoxy)carbene complexes, amines and alkynes

The synthesis of novel p-aminophenols 19a-o and p-quinones 21a-i was carried out by an aminolysis reaction/[3 + 2+1] cycloaddition cascade process of alpha-alkoxyvinyl (ethoxy) Fischer carbene complexes of group 6 metals (M = Cr, Mo, W), primary and secondary amines and terminal alkynes. The multicomponent reaction of carbenes la-c with morpholine (6a) and piperidine (6c), respectively, and terminal alkynes 17a-d only afforded the 4-aminophenols 19a-o in moderated yields. The products bore the terminal alkyne substituent at the ortho position of the hydroxyl group. These one-pot reactions showed highly regio- and chemoselectivity, favoring the benzannulation products. When carbene complexes la-c were reacted with primary amines 10a-c and alkynes 17a-c under the same conditions, the cascade process led to the formation of p-quinones 21a-21i, in moderate yields. The regiochemistry of the compounds was established by NOE experiments, and the structures of morpholinocarbene 7a, p-aminophenols 19b, 19d and p-quinone 21b were confirmed by single-crystal X-ray diffraction.

Transition-Metal-Free Functionalization of Saturated and Unsaturated Amines to Bioactive Alkaloids Mediated by Sodium Chlorite

New approaches to the synthesis of alkaloids through the straightforward functionalization of C(sp(3))-H and C(sp(2))=C(sp(2)) bonds of simple five- and six-membered-ring N-heterocycles are highlighted. The direct functionalization of pre-existing N-heterocycles to advanced alkaloids intermediates is a chemical operation that commonly requires the intervention of transition or precious metals. Regardless the inherent unwanted waste production, the high economical cost of many transition-metal catalysts limits their use globally. Here, we account our efforts directed toward the synthesis of bioactive alkaloids under an economic and ecological fashion by using NaClO2 as the key activating or oxidizing reagent that substitutes the use of transition-metal catalysts. While undesired metal wastes are collected during the extraction process of a transition-metal-catalyzed reaction, innocuous NaCl is the commonly product waste when NaClO2 is employed in our chemical transformations. Beginning with the synthesis of 2,3-epoxyamides from allyl amines, we concluded with the functionalization of multiple and remote C(sp(3))-H and C(sp(3))-C(sp(3)) bonds in piperidine rings that enabled the preparation of important bioactive alkaloids. For the latter functionalization, a precise amount of co-oxidant reagent (NaOCl) and radical 2,2,6,6-tetramethylpiperidinyloxy (TEMPO) were needed.

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.

Synthesis of (3S,4S,5S)-trihydroxylpiperidine derivatives as enzyme stabilizers to improve therapeutic enzyme activity in Fabry patient cell lines

A series of 3S,4S,5S-trihydroxylated piperidines bearing structural diversity at C-2 or C-6 positions has been synthesized and tested to determine their ability to stabilize the activity of recombinant human alpha-Galactosidase A (rh-alpha-Gal A). Hit molecules were identified by rapid inhibitory activity screening, and then further investigated for their ability to protect this enzyme from thermo-induced denaturation and enhance its activity in Fabry patient cell lines. Our study resulted in the identification of a new class of small molecules as enzyme stabilizers for the potential treatment of Fabry disease. Of these, stabilizer 21 was the most effective, showing a 12-fold increase in rh-alpha-Gal A activity in Fabry disease cell lines. (C) 2017 Elsevier Masson SAS. All rights reserved.
