N-benzyl-5-hydroxy-3-pyrrolidin-2-one by hydrogen peroxide oxidation of n-benzyl-3-phenylseleno-2-pyrrolidinone

Using the known peroxide oxidation of N-benzyl-3-phenylseleno-2-pyrrolidinone with 30% hydrogen peroxide at – 5 degrees C after 3.5 h, we prepared the expected N-benzyl-3-pyrrolin-2-one. However, reaction with 30% hydrogen peroxide for 12 h (-5 degrees C -> ambient) gave the unexpected product N-benzyl-5-hydroxy-3-pyrrolidin2-one in 84% isolated yield. This procedure is a new synthetic route to N-benzyl-5hydroxy-3-pyrrolidin-2-one.

Effect of Particle Wettability and Particle Concentration on the Enzymatic Dehydration of n-Octanaloxime in Pickering Emulsions

Pickering emulsion systems have emerged as platforms for the synthesis of organic molecules in biphasic biocatalysis. Herein, the catalytic performance was evaluated for biotransformation using whole cells exemplified for the dehydration of n-octanaloxime to n-octanenitrile catalysed by an aldoxime dehydratase (OxdB) overexpressed in E. coli. This study was carried out in Pickering emulsions stabilised solely with silica particles of different hydrophobicity. We correlate, for the first time, the properties of the emulsions with the conversion of the reaction, thus gaining an insight into the impact of the particle wettability and particle concentration. When comparing two emulsions of different type with similar stability and droplet diameter, the oil-in-water (o/w) system displayed a higher conversion than the water-in-oil (w/o) system, despite the conversion in both cases being higher than that in a classic two-phase system. Furthermore, an increase in particle concentration prior to emulsification resulted in an increase of the interfacial area and hence a higher conversion.

Enhanced energy density of poly(arylene ether nitriles) composites filled with surface engineered BaTiO3 nanoparticles

The introduction of nano-sized BaTiO3 (BT) into polymer host matrices brings about promising dielectric and energy storage properties. However, pristine BT tends to aggregate and is difficult to be compatible with polymer matrices, thus requiring surface modification of BT nanoparticles. In this work, gamma-aminopropyl triethoxysilane (KH550) was grafted onto the surface of BT as a shell and amino-functionalized core-shell KH550@BT nanoparticles have been successfully prepared. Thereafter, poly(arylene ether nitrile) (PEN) has been chosen as polymer matrix due to its excellent thermal properties, and xKH550@BT/(1-x)PEN composite films were prepared by solution casting film formation method. The energy density of KH550@BTIPEN composites with 30 wt.% filler loading is 1.30 J cm(-3) (eta = 61.32 %) at 150 MV m(-1), more than 36.84 % increase when compared with pristine PEN polymer (0.95 J cm(-3) at 170 MV m(-1)). Temperature-dependent and frequency-dependent D-E loops confirmed that KH550@BTIPEN composites possess good temperature and frequency stability. (C) 2020 Elsevier B.V. All rights reserved.

The requirement for cobalt in vitamin B-12: A paradigm for protein metalation

Vitamin B-12, cobalamin, is a cobalt-containing ring-contracted modified tetrapyrrole that represents one of the most complex small molecules made by nature. In prokaryotes it is utilised as a cofactor, coenzyme, light sensor and gene regulator yet has a restricted role in assisting only two enzymes within specific eukaryotes including mammals. This deployment disparity is reflected in another unique attribute of vitamin B-12 in that its biosynthesis is limited to only certain prokaryotes, with synthesisers pivotal in establishing mutualistic microbial communities. The core component of cobalamin is the corrin macrocycle that acts as the main ligand for the cobalt. Within this review we investigate why cobalt is paired specifically with the corrin ring, how cobalt is inserted during the biosynthetic process, how cobalt is made available within the cell and explore the cellular control of cobalt and cobalamin levels. The partitioning of cobalt for cobalamin biosynthesis exemplifies how cells assist metalation.

Synthesis of Nitroxide-Annulated Carbocycles and Heterocycles

New, pyrroline nitroxide annulated lactones, polycycles, and maleimide were synthesized by classical and microwave-assisted methodology. We report the application of the metathesis reaction in the presence of nitroxide yielding a pyrroline nitroxide condensed 1,4-benzoquinone as a paramagnetic dienophile. The formation of the isoselenazolone-fused pyrroline ring system was examined and different reactivity was observed with pyrrolin-1-oxyl and pyrroline derivatives.

Synthesis of Novel 3D-Rich alpha-Amino Acid-Derived 3-Pyrazolidinones

Synthetic approaches towards novel 3-pyrazolidinone derivatives functionalized at positions N(1) and/or C(5) were studied. 5-Aminoalkyl-3-pyrazolidinones were prepared in four steps from N-protected glycines via Masamune-Claisen homologation, reduction, O-mesylation, and cyclisation with a hydrazine derivative. The free amines were prepared by acidolytic deprotection. Title compound was also prepared by ‘ring switching’ transformation of N-Boc-pyrrolin-2(5H)-one with hydrazine hydrate. Hydrogenolytic deprotection of 5-(N-alkyl-N-Cbz-aminomethyl) pyrazolidine-3-ones followed by cyclisation with 1,1′-carbonyldiimidazole (CDI) gave two novel representatives of perhydroimidazo[1,5-b] pyrazole, which is an almost unexplored heterocyclic system. Amidation of 3-oxopyrazolidine-5-carboxylic acid gave the corresponding carboxamides in moderate yields. Diastereomeric non-racemic carboxamides obtained from (S)-AlaOMe and (S)-ProOMe were separated by MPLC.
