Stereodivergent Synthesis of Trisubstituted Enamides: Direct Access to Both Pure Geometrical Isomers

A stereodivergent strategy has been developed to access either (E)- or (Z)-isomers of trisubstituted enamides. Starting from an extensive range of ketones, it was possible to synthesize and isolate the desired pure isomer by switching the reaction conditions. Lewis acid activation enables the formation of the (E)-isomers in high stereoselectivity (>90:10) and good yields. On the other hand, the use of a Br¡ãnsted acid allows the preparation of the (Z)-isomers, again in high selectivity (up to 99:1), with moderate yields.

Enantioselective synthesis of 2-substituted 4-aminobutanoic acid (GABA) analogues via cyanomethylation of chiral enolates

Cyanomethylation by bromoacetonitrile of sodium or lithium enolates derived from (4S,5R)-3-acyl-4-methyl-5-phenyl-1,3-oxazolidin-2-ones usually shows good stereoselecrivity; although the reaction of 3-(3-carboxypropanoyl)oxazolidinone 5d is exceptionally unselective, the 3-(pent-4-enoyl)- and 3-(3,4-dimethoxyhydrodnnamoyl)oxazolidinones 5e and 5f are found to be effective synthetic equivalents of 5d. The cyanomethylation products can be converted into 2-substituted derivatives of 4-aminobutanoic acid (gamma-aminobutyric acid, GABA) by the alkaline hydrolysis of the oxazolidinone chiral auxiliary followed by hydrogenation of the cyano group.

Synthesis of a diastereomer of the marine macrolide lytophilippine A

The synthesis of a diastereomer of lytophilippine A required 22 longest linear steps using known building blocks. Cross-metathesis/asymmetric aldol addition and regioselective esterification/ring-closing metathesis served as efficient combi tools for scaffold construction. Detailed NMR investigations in different solvent (systems) provide evidence for a deep-seated configurational misassignment of the molecule named lytophilippine A.

Synthetic Polyamines to Regulate mRNA Translation through the Preservative Binding of Eukaryotic Initiation Factor 4E to the Cap Structure

Polyion complexes (PICs) of mRNA with synthetic polyamines are receiving increasing attention as mRNA delivery vehicles, and the search for polyamine structure maximizing the translational efficiency of complexed mRNA becomes a critical research topic. Herein, we discovered that fine-tuning of the protonation status of synthetic polyamines can regulate mRNA translation through the preservative binding of eukaryotic initiation factor 4E to m7GpppN (cap structure) on the 5? end of mRNA. A series of polyamines with varied numbers of aminoethylene repeats in their side chains were prepared by an aminolysis reaction of poly(beta-benzyl-l-aspartate) and paired with mRNA to form PICs. PICs formed from polyamines with higher numbers of aminoethylene repeats preserved the original translational efficiency to naked mRNA, whereas the efficiency significantly dropped by decreasing the number of aminoethylene repeats in the polyamines. Immunoprecipitation assays using anti-eIF4E antibodies revealed that the binding affinity of eIF4E to the cap structure of mRNA in the PIC was sensitive to the number of charged aminoethylene repeats in the polyamine side chain and was strongly correlated with their translational efficiency. These results indicate that the fine-tuning of the polyamine structure plays a critical role in maximizing the translational efficiency of mRNA in the PICs having potential utility as mRNA delivery vehicles.

Synthesis and conformational analysis of a dimerising eight-membered lactam dipeptide

The eight-membered lactam dipeptide (3R,8R)-3-acetylamino-8-methoxycarbamoylazocan-2-one was prepared from the L-serine derived (4S)-3-tert-butyloxycarbonyl-4-formyl-2,2-dimethyl-1,3-oxazolidine in 12 steps and 27% overall yield. An extensive conformational analysis both in the solid state and in solution, using NMR, IR and vapour pressure osmometry, was conducted. It was shown that the constrained dipeptide exists in a semi-extended conformation and exhibits a head-to-tail self-recognition (Kdim 100 ¡À 20 dm3 mol-1 in CDCl2CDCl2). This dimerisation appears to be a general phenomenon in a series of cis-disubstituted medium-ring lactam dipeptides. The Royal Society of Chemistry 2000.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. HPLC of Formula: C10H11NO2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 102029-44-7, in my other articles.

Ni@Pd nanoparticles supported on ionic liquid-functionalized KCC-1 as robust and recyclable nanocatalysts for cycloaddition of propargylic amines and CO2

Novel heterogeneous catalyst systems comprised of a fibrous nanosilica-supported nano-Ni@Pd-based ionic liquid (KCC-1/IL/Ni@Pd) are described for the cyclization of propargylic amines with CO2 to provide 2-oxazolidinones. KCC-1 with high surface area was functionalized with IL acting as a robust anchor so that the nano-Ni@Pd was well dispersed on the fibres of the KCC-1 microspheres, without aggregation. Because of the amplification effect of IL, high loading capacities of the nanocatalysts were achieved. The reported synthesis includes several advantages like solvent-free conditions, operational simplicity, short reaction times, environmentally benign reaction conditions, cost effectiveness, high atom economy and excellent yields, making it a genuinely green protocol.

N-Acyl and N-sulfonyloxazolidine-2,4-diones are pseudo-irreversible inhibitors of serine proteases

The synthesis, inhibitory activity and mode of action of oxazolidine-2,4-diones against porcine pancreatic elastase, here used as a model for human neutrophil elastase, are reported. The nature of N-substitution at the oxazolidine-2,4-dione scaffold has large effect on the inhibitory potency against elastase. N-Acyl and N-sulfonyloxazolidine-2,4-diones emerged as potent pseudo-irreversible inhibitors, displaying high second-order rate constants for PPE inactivation. The title compounds were also shown to be potent inhibitors of human neutrophil elastase (HNE) and proteinase-3, and weak inhibitors of human cathepsin G. The results herein presented show that the oxazolidine-2,4-diones represent a new promising class of serine protease inhibitors.
