One‐Step and Universal Strategy for the Synthesis of Hypermodified Uracil Phosphoramidites acp3U and cmnm5U

Chemistry – A European Journal, Volume 32, Issue 16, 25 April 2026.
One‐step, highly efficient, and scalable synthesis of acp3U phosphoramidite is described, as well as a new alternative synthesis of cmnm5U phosphoramidite from a highly versatile intermediate. Latter could be scaled‐up, split, and aliquots turned simultaneously into cmnm5U, nm5U, and mnm5U.

Triptindane‐9,10,11‐triol: Threefold Hydride Transfer from Lithium Aluminum Hydride as the Key Step to C3‐Symmetrically Trifunctionalized Tribenzo[3.3.3]propellanes

European Journal of Organic Chemistry, Volume 29, Issue 15, 22 April 2026.
Threefold reduction of 9,10,11‐triptindanetrione with LiAlH4 or NaBH4 yields exclusively the C3‐symmetric triol, suggesting an intracomplex (“rolling”) mechanism. However, use of LiAlH4/LiAlD4 (1 : 1) reveals a preceding hydride exchange. Mechanistic implications are discussed including the reduction of the related diketone.

Modulating IDO1 and TDO Inhibition Through Structural Modification of Diaryl Hydroxylamines

ChemMedChem, Volume 21, Issue 7, 14 April 2026.
Diaryl hydroxylamines have emerged as promising scaffolds for targeting the tryptophan‐catabolizing enzymes indoleamine 2,3‐dioxygenase 1 (IDO1) and tryptophan 2,3‐dioxygenase (TDO), key drivers of tumor immune escape. Building on the reported dual IDO1/TDO inhibitory activity of O‐((3,5‐difluorophenyl)(phenyl)methyl)hydroxylamine, a series of diaryl ...

Methanimine as a sink in the HCN and HNC solid state hydrogenation network

Astronomy & Astrophysics
Aims. We aim to provide a systematic and quantitative description of the hydrogenation network connecting HCN and HNC to methylamine on interstellar water ices, and to identify the dominant reaction pathways and potential bottlenecks. Methods.

Time-resolved imaging of non-diffusive carrier transport in long-lifetime halide perovskite thin films

, 2019
Owing to their exceptional semiconducting properties, hybrid inorganic-organic perovskites show great promise as photovoltaic absorbers. In these materials, long-range diffusion of charge carriers allows for most of the photogenerated carriers to ...

Pulsed electrosynthesis orthogonally optimizes C‒N coupling and hydrogenation for amine production with a molecular catalyst

Nature Communications
Co-electrolysis of CO2 and nitrate offers a sustainable route to organic amines but suffers from a kinetic mismatch between C-N coupling and hydrogenation steps under static conditions.
