Addition of Di(trimethylsilyl) Phosphite to Schiff Bases of 2,5-Diformylfuran [PDF]
A series of 2,5-Furanyl-bis-(aminomethylphosphonic Acids) has been synthesized by the addition of di(trimethylsilyl) phosphite to azomethine bond of achiral Schiff bases derved from 2,5-diformylfuran.

Focus on chirality of HIV-1 non-nucleoside reverse transcriptase inhibitors [PDF]
Chiral HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) are of great interest since one enantiomer is often more potent than the corresponding counterpart against the HIV-1 wild type (WT) and the HIV-1 drug resistant mutant strains.

Femtosecond dynamics of hydrogen elimination: benzene formation from cyclohexadiene [PDF]
Using femtosecond-resolved mass spectrometry in a molecular beam, we report real-time study of the hydrogen elimination reaction of 1,4-cyclohexadiene. The experimental observation of the ultrafast stepwise H-elimination elucidates the reaction dynamics ...

Ortho‐Quinone Methide Driven Synthesis of New O,N‐ or N,N‐Heterocycles
To synthesize functionalized Mannich bases that can serve two different types of ortho‐quinone methide (o‐QM) intermediates, 2‐naphthol and 6‐hydroxyquinoline were reacted with salicylic aldehyde in the presence of morpholine.

Chiral Aspects of Local Anesthetics
Thanks to the progress made in chemical technology (particularly in the methodologies of stereoselective syntheses and analyses) along with regulatory measures, the number of new chiral drugs registered in the form of pure enantiomers has increased over ...

Fast and Accurate Prediction of Refractive Index of Organic Liquids with Graph Machines
The refractive index (RI) of liquids is a key physical property of molecular compounds and materials. In addition to its ubiquitous role in physics, it is also exploited to impart specific optical properties (transparency, opacity, and gloss) to ...

Diels–Alder reaction of β-fluoro-β-nitrostyrenes with cyclic dienes
The Diels–Alder reaction of β-fluoro-β-nitrostyrenes with cyclic 1,3-dienes was investigated. A series of novel monofluorinated norbornenes was prepared in up to 97% yield.
