N-(3-ethynylphenyl)maleimide [PDF]

, 1990
Acetylene terminated aspartimides are prepared using two methods. In the first, an amino-substituted aromatic acetylene is reacted with an aromatic bismaleimide in a solvent of glacial acetic acid and/or m-cresol.

Intracellular and Extracellular Efficacy of Homoisoflavone Derivatives Against Mycobacterium Tuberculosis: Progress Toward Novel Antitubercular Agents

ChemMedChem, EarlyView.
A series of 42 homoisoflavones were synthesized and evaluated against Mycobacterium tuberculosis (Mtb). Three derivatives showed potent inhibition of Mtb strains. Evaluation in infected macrophages revealed promising intracellular activity, where one derivative featuring a nitrofuranyl and piperidine group emerges as the most promising.

Determination of Diketopiperazine Formation During the Solid‐Phase Synthesis of C‐Terminal Acid Peptides

Chemistry–Methods, EarlyView.
Diketopiperazine formation (DKP) is one of the most serious side reactions during peptide synthesis. An accurate method to determine the DKP formation in peptide synthesis on Wang resin is reported. Furthermore, the strategies to minimize this side reaction and side products lacking C‐terminal amino acids are described. Diketopiperazine formation (DKP)

The [3,3]‐Sigmatropic Allyl Cyanate–Isocyanate Rearrangement on Levoglucosenone Derivatives Stereoselectively Provides 4‐Deoxy‐4‐Aminosugars

Chemistry–Methods, EarlyView.
The Ichikawa rearrangement of allyl cyanates obtained in situ from levoglucosenone‐derived allyl carbamates allows the synthesis of unique 4‐deoxy‐4‐amino‐d‐allose derivatives with complete chirality transfer in a metal‐free three‐step, one‐pot manner.

Vinyl stilbazoles [PDF]

, 1986
Vinyl pyridines including vinyl stilbazole materials and vinyl styrylpyridine oligomer materials are disclosed. These vinylpyridines form copolymers with bismaleimides which copolymers have good fire retardancy and decreased brittleness.

Molecular Fragmentation as a Strategy to Access Hyperpolarized Compounds from Para‐Hydrogen

ChemPhysChem, EarlyView.
Hyperpolarization using para‐hydrogen is a simple and cost‐effective method to dramatically increase sensitivity in magnetic resonance. When combined with chemical reactions that generate smaller fragments, a much wider array of different hyperpolarized molecules can be accessed.
