N-Heterocyclic Carbene-Catalyzed Decarboxylative Alkylation of Aldehydes.
Journal of the American Chemical Society, 2019 We found that N-heterocyclic carbene catalysis promoted the unprecedented decarboxylative coupling of aryl aldehydes and tertiary or secondary alkyl carboxylic acid-derived redox-active esters to produce aryl alkyl ketones.

Synthesis, screening, and sequencing of cysteine-rich one-bead one-compound peptide libraries. [PDF]
, 2008 Cysteine-rich peptides are valued as tags for biarsenical fluorophores and as environmentally important reagents for binding toxic heavy metals. Due to the inherent difficulties created by cysteine, the power of one-bead one-compound (OBOC) libraries has

Direct C(sp2)–H alkylation of unactivated arenes enabled by photoinduced Pd catalysis
Nature Communications, 2020 Direct catalytic C(sp2)–H alkylation of unactivated arenes with alkyl halides remains elusive despite the progress in C-H functionalization. Here, the authors report the catalytic C(sp2)–H alkylation of unactivated arenes with alkyl bromides via visible ...

Novel sulfur and selenium containing bis-α-amino acids from 4-hydroxyproline [PDF]
, 2010 The synthesis of new substituted prolines carrying at C-4 a second α-amino acid residue is reported. The amino acid, l-cysteine or l-selenocysteine, is linked to the proline ring through the sulfur or the selenium atom, respectively.

Modeling of Benzene with Ethylene Alkylation
MATEC Web of Conferences, 2016 The paper considers the benzene alkylation with ethylene model development with the use of zeolite catalyst. A list of reactions occurring in the alkylation reactor was made and the thermodynamic possibility of determination of these reactions by the ...

Synthesis and structure of novel tripodal ligands based on tetrazol-5-thioles
Журнал Белорусского государственного университета: Химия, 2022 Novel tripodal ligands (R1N4CS)3CH, where R1 = Me, Ph, were synthesised by alkylation of 1-R-tetrazol-5-thioles with iodoform in alkaline media. These ligands were identified based on data of elemental analysis, nuclear magnetic resonance spectroscopy ...

The NADPH-Dependent thioredoxin reductase C-2-Cys peroxiredoxin redox system modulates the activity of thioredoxin x in arabidopsis chloroplasts [PDF]
, 2018 The chloroplast redox network is composed of a complex set of thioredoxins (Trxs), reduced by ferredoxin (Fdx) via a Fdx-dependent Trx reductase (FTR), and an NADPH-dependent Trx reductase with a joint Trx domain, NTRC, which efficiently reduces 2-Cys ...
