Reaction between Indazole and Pd-Bound Isocyanides—A Theoretical Mechanistic Study

Molecules, 2018
The mechanism of the addition of indazole (Ind)—a bifunctional aromatic N,NH-nucleophile—to cyclohexyl isocyanide coordinated to the palladium(II) center in the model complex cis-[PdCl2(CNMe)(CNCy)] (1) to give the corresponding aminocarbene ...

The reaction of arylmethyl isocyanides and arylmethylamines with xanthate esters: a facile and unexpected synthesis of carbamothioates

Beilstein Journal of Organic Chemistry, 2020
An unexpected formation of carbamothioates by a sodium hydride-mediated reaction of arylmethyl isocyanides with xanthate esters in DMF is reported. The products thus obtained were compared with the carbamothioates obtained by the sodium hydride-mediated ...

Isocyanide 2.0

Green Chemistry, 2020
Isocyanides are important chemicals, with limited availability, thus reducing their general use. Our highly improved isocyanide synthesis performed on mole to μ-mole scale, individually or in a 96-well parallel fashion enables unprecedented exploration of novel chemistries.

A Conserved Isoleucine Gates the Diffusion of CO and O2 to the Active Site of NiFe CO‐Dehydrogenase

Angewandte Chemie International Edition, EarlyView.
A combination of protein film electrochemistry and site‐directed mutagenesis shows that isoleucine 563 (numbering of Thermococcus sp. AM4) gates the arrival of both CO and O2 to the active site of the nickel‐iron CO dehydrogenases. Mutations at this position increase the resistance to O2 at the cost of a slower reaction with CO.

Dehydroabietylamine derived bistetrazoles from ultrasound-assisted pseudo-seven-component Ugi reactions act as efficient and selective inhibitors of cholinesterases

European Journal of Medicinal Chemistry Reports
The reaction of dehydroabiethylamine (DHA) with isocyanides and formaldehyde produces varying products depending on the conditions employed. In a 4-component Ugi reaction using benzyl isocyanide, paraformaldehyde, and TMS-azide, the anticipated tetrazole

Isocyanides inhibit [Fe]-hydrogenase with very high affinity [PDF]

, 2010
[Fe]-Hydrogenase catalyzes the reversible activation of H2. CO and CN− inhibit this enzyme with low affinity (Ki≅0.1mM) by binding to the iron site of the bound iron-guanyrylpyridinol cofactor.

Synthesis and Activity‐Based Protein Profiling Identifies Aldo‐Keto Reductase 1C3 as Target Protein of Myxoglucamides

Angewandte Chemie International Edition, EarlyView.
Myxoglucamide A—a novel glycolipopeptide isolated from myxobacteria—was synthesized, and activity‐based protein profiling identified aldo‐keto reductase 1C3 (AKR1C3) as its main target in human cells. Structure‐activity relationship studies, together with biophysical characterization and X‐ray crystallography, elucidated the structural basis of AKR1C3 ...

Synthesis of N-7-Substituted Purines from Imidazole Precursors

Molecules, 1999
Synthesis of purines and purine mono-1-oxides from the respective 5-substituted 4-nitroimidazole derivatives is described. The commercially available 4-nitroimidazole, in a few simple steps (including Vicarious Nucleophilic Substitution of Hydrogen), was
