Dipeptide analogues containing 4-ethoxy-3-pyrrolin-2-ones

Pyrrolidine-2,4-diones (1) are naturally occurring analogues of amino acids. We herein present a facile synthesis of N-acylated, O-alkylated pyrrolin-2-ones (2) in high yield and excellent enantiopurity. Molecular mechanics calculations suggest that the resulting dipeptide analogues adopt a linear, extended conformation.

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. you can also check out more blogs about 57-71-6. Safety of Diacetyl Monoxime.

Nitrile-Facilitated Proton Transfer for Enhanced Oxygen Reduction by Hybrid Electrocatalysts

To enable efficient energy conversion schemes for our society in the future, breakthroughs in precise thermodynamic and kinetic control of the underlying redox reactions are necessary. Hybrid bilayer membranes (HBMs), comprising a self-assembled monolayer (SAM) covered by a lipid membrane, have been developed recently to regulate the performance of HBM-embedded electrocatalysts. A major technological roadblock in HBM development is the inability to facilitate proton transfer under alkaline conditions where nonprecious metal (NPM) catalysts can rival the performance of their precious metal counterparts. Here, we synthesized proton carriers bearing nitrile groups found in protonophores. These bioinspired proton carriers can facilitate transmembrane proton delivery to an HBM-supported Cu oxygen reduction reaction (ORR) catalyst under alkaline conditions. Our stimuli-responsive proton regulators can turn on the activity of the ORR catalyst on-demand, thereby opening doors to investigate how proton transfer kinetics govern the performance of electrocatalysts for renewable energy conversion processes.

Synthetic Exploration of alpha-Diazo gamma-Butyrolactams

DIazo transfer reaction onto -butyrolactams (activated by -ethyloxalylation) gave rare -diazo -butyrolactams. Decomposition of the latter by Rh-2(OAc)(4) in the presence of alcohols and water gave products of O-H insertion of the respective metal-cabene species. Silver triflate (1 mol-%) was found to convert the -butyrolactams investigated into 1,5-dihydro-2H-pyrrol-2-ones which represent versatile building blocks. Particular instability was noted for -diazo -butyrolactams bearing alkyl or o-substituted aryl substituents on the nitrogen atom. These were found to dimerize in solution or upon storage at room temperature to give fully conjugated bis-hydrazones along with the loss of a nitrogen molecule.

Construction of Vicinal Tetrasubstituted Stereogenic Centers via a Mannich-Type Organocatalyzed Addition of Delta(2)-Pyrrolin-4-ones to Isatin Imines

Racemic (2)-pyrrolin-4-ones (i.e. 4-pyrrolones), easily available in two steps from N-protected -amino acids, undergo organocatalysed asymmetric Mannich-type addition to isatin-derived ketimines to furnish the non-racemic oxindole-(2)-pyrrolin-4-one adducts, stereoselectively (up to 96% ee, dr15:1). The oxindole-pyrrolone products feature vicinal tetrasubstituted carbon stereocenters. The developed protocol has a broad substrate scope and tolerates diverse substituents at position C-5 in 4-pyrrolones and at positions N-1 and C-5/7 in isatin imines.

Instant killing of pathogenic chytrid fungi by disposable nitrile gloves prevents disease transmission between amphibians

To prevent transmission of the pathogenic chytrid fungi Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal), hygiene protocols prescribe the single use of disposable gloves for handling amphibians. We discovered that rinse water from nitrile gloves instantly kills 99% of Bd and Bsal zoospores. Transmission experiments using midwife toads (Alytes obstetricans) and Bd, and Alpine newts (Ichthyosaura alpestris) and Bsal, show that the use of the same pair of gloves for 2 subsequent individuals does not result in significant transmission of any chytrid fungus. In contrast, handling infected amphibians bare-handed caused transmission of Bsal in 4 out of 10 replicates, but did not result in transmission of Bd. Based on the manufacturer’s information, high resolution mass spectrometry (HRMS) and colorimetric tests, calcium lactate and calcium nitrate were identified as compounds with antifungal activity against both Bd and Bsal. These findings corroborate the importance of wearing gloves as an important sanitary measure in amphibian disease prevention. If the highly recommended single use of gloves is not possible, handling multiple post-metamorphic amphibians with the same pair of nitrile gloves should still be preferred above bare-handed manipulation.

Morphology evolution, mechanical properties, Mullins effect, and its reversibility of polylactide/nitrile butadiene rubber thermoplastic vulcanizates plasticized by dioctyl phthalate

Thermoplastic vulcanizates (TPVs) based on polylactide (PLA)/nitrile butadiene rubber (NBR) blends were prepared by dynamic vulcanization where the PLA phase was plasticized by dioctyl phthalate (DOP), and the influence of DOP dosage on mechanical properties, morphology evolution, Mullins effect, and its reversibility were investigated systematically. The experimental results indicated that the mechanical properties of PLA/NBR TPVs were improved significantly with the addition of DOP. Compared with that of the PLA/NBR TPVs, the Shore A hardness was decreased obviously, while the elongation at break was increased slightly with increasing DOP dosage. Mullins effect results showed that the TPVs incorporated with DOP had the relatively lower stress-softening effect. The recovery ability of the maximum stress could be remarkably enhanced by increasing heat treatment temperature. Morphology studies showed that the network microstructure of the co-continuous phases was denser with the increasing dynamic vulcanization time; however, the network microstructure of the co-continuous was changed slightly with the addition of DOP.

Copper- and DMF-mediated switchable oxidative C-H cyanation and formylation of imidazo[1,2-a]pyridines using ammonium iodide

The cyanation and formylation of imidazo[1,2-a]pyridines were developed under copper-mediated oxidative conditions using ammonium iodide and DMF as a nontoxic combined cyano-group source and DMF as a formylation reagent. Mechanistic studies indicate that the cyanation of imidazo[1,2-a]pyridines proceeds through a two-step sequence: initial iodination and then cyanation. The cyanation has a broad substrate scope and high functional group tolerance, and can be safely conducted on a gram scale. A novel copper-mediated formylation using the widely available DMF as the formylation reagent and environmentally friendly molecular oxygen as the oxidant has also been developed. This protocol also provided a convenient approach for the synthesis of clinically used saripidem.
