Toward polymers with oxazolidin-2-one building blocks through tetra-n-butyl-ammonium halides (Cl, Br, I) catalyzed coupling of epoxides with isocyanates

The selectivity of the reaction of 4,4-methylene diphenyl diisocyanate MDI with o-cresyl glycidyl ether OCGE yielding oxazolidin-2-one and isocyanurates, and applying tetra-n-butyl ammonium halide as catalysts is higher in the order chloride, bromide, iodide. The dominant reaction pathways were inferred from the reactivity of the system with various ratios of MDI to OCGE, and using IR spectroscopy to monitor the progress. The reaction proceeds in several steps with initial nucleophilic attack of the halide on the epoxide yielding an alkoxide intermediate. The alkoxide reacts with isocyanate to yield a carbamato intermediate that may either ring close to form oxazolidinone or catalytically form isocyanurates by addition of more isocyanate and backbiting. The formation of isocyanurate is the reaction with the lowest activation barrier. Isocyanurate acts also as an isocyanate precursor as it is ring opened by the alkoxide intermediates in a slower consecutive process. Oxazolidinone modified epoxy prepolymers could be prepared from bisphenol A diglycidyl ether and MDI.

Thermal degradation of novel piperazine-based amine blends for CO2 capture

36 novel piperazine (PZ)-based amine blends were investigated for their thermal stability for CO2 capture. These amines include 7 imidazoles, 8 cyclic and long-chain diamines, 12 tertiary amines, 4 hindered amines, 3 hindered and tertiary amino acids, and 2 ether amines that were selected based on known amine structure-property relationships and their potential for industrial application. 18 thermally stable PZ-based amine blends were identified based on their degradation rates in CO2 loaded solutions at 150 and 175 C. Degradation mechanisms were studied to understand the relationships between the structure and thermal stability of the blended amines of the blends.

Pyrrolizidine Alkaloids

Naturally occurring pyrrolizidine alkaloids (PAs) are isolated from plants and other sources. The interest of the scientific community in these compounds owes itself to their high toxicity and biological activity, as well as to the challenge of synthesizing their pyrrolizidine scaffold. This review encompasses a wide range of topics found in the literature from 1995 to date, including the occurrence, biosynthesis, toxicity (hepatotoxicity, genotoxicity, and tumorigenicity), biological activity, and pharmacological properties (glycosidase inhibitory activity) of these secondary metabolites. Particular attention is given to the chemistry of PAs, addressing general strategies for formal and total syntheses via amino-based substrates, pyrroles, and pyrrolidine-based derivatives.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: Oxazolidin-2-one, you can also check out more blogs about497-25-6

Enantioselective Oxidative (4+3) Cycloadditions between Allenamides and Furans through Bifunctional Hydrogen-Bonding/Ion-Pairing Interactions

BINOL-based N-trifluoromethanesulfonyl phosphoramides catalyze the enantioselective (4+3) cycloaddition between furans and oxyallyl cations, the latter being generated in situ by oxidation of allenamides. The chiral organic phosphoramide counteranion is proposed to engage in the activation of the oxyallyl cation intermediate through cooperative hydrogen-bonding and ion-pairing interactions, enabling an efficient chirality transfer that provide the final adducts with high diastereo- and enantioselectivities. Remarkably, the reaction shows a wide substrate scope that includes a variety of substituted allenamides and furans.

Fluorinated PEG-Polypeptide Polyplex Micelles Have Good Serum-Resistance and Low Cytotoxicity for Gene Delivery

A novel PEGylation polypeptide, poly(ethylene glycol)-b-poly(l-lysine)-b-poly(l-cysteine) (PEG-PLL-PCys) triblock copolymer is synthesized via the sequential ring-opening polymerization of amino acid N-carboxyanhydrides initiated by methoxypolyethylene glycol amine (mPEG-NH2, Mw is 2 kDa). Subsequently, the obtained polypeptide is partially conjugated with fluorocarbon chains via disulfide exchange reaction. PLL segment can condense plasmid DNA through an electrostatic force to form a complex core, PEG segment surrounding the complex like a corona can prevent the complex from precipitation and reduce the adsorption of serum, while PCys segment with fluorocarbon can enhance the cellular uptake and the stability of the formed polyplex micelles in physiological conditions. Experiment results exhibit that the fluorinated polypeptides have low cytotoxicity and good gene transfection efficiency even in the presence of 50% fetal bovine serum. (Figure presented.).
