Azide‐to‐Diazo Transformation Facilitated by Michael Addition via Phosphazide Formation

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
A new type of Michael addition based on azide‐to‐diazo conversion is disclosed. This unusual transformation proceeds via 1,4‐addition accompanied by N─N bond cleavage of phosphazide intermediates under practical conditions. The high versatility of the resulting Michael adducts enables the synthesis of a wide variety of organonitrogen compounds ...

Strategies Toward Accessing Enantioenriched (Hetero)Benzo‐Fused 5‐ and 6‐ Membered Rings via Intermolecular Carbometalation

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
The use of transition‐metal catalysts and design of chiral ligands have allowed chemists to access highly functionalized benzofused 5‐ and 6‐ membered rings in high yield and enantioselectivity. A common strategy used relies on an intermolecular carbometalation across alkynes and olefins, usually followed by a subsequent intramolecular carbometalation.

Engineering of CoA‐Acylating Butyraldehyde Dehydrogenase for Enhanced 1,3‐Butanediol Production in Escherichia coli

Biotechnology and Bioengineering, Volume 123, Issue 6, Page 1605-1614, June 2026.
ABSTRACT Microbial production of 1,3‐butanediol (1,3‐BDO) offers a renewable route to this versatile C4 chemical. However, the low performance of CoA‐acylating butyraldehyde dehydrogenase (Bld), which contains a catalytic cysteine, limits efficient production in recombinant Escherichia coli (E. coli).

NIR Calibrations for Soybean Seeds and Soy Food Composition Analysis: Total Carbohydrates, Oil, Proteins and Water Contents [PDF]

, 2011
Conventional chemical analysis techniques are expensive, time consuming, and often destructive. The non-invasive Near Infrared (NIR) technology was introduced over the last decades for wide-scale, inexpensive chemical analysis of food and crop seed ...

Selective Rh(II)‐Catalyzed Intermolecular Oxyamidation and Acid‐Promoted Nucleophilic Cyclization Cascade of Enamides

ChemistryEurope, Volume 4, Issue 6, June 2026.
A structurally diverse series of 1‐amino‐izidine scaffolds was accessed through a cascade process combining rhodium‐catalyzed nitrene‐transfer oxyamidation with subsequent nucleophilic cyclization under acidic conditions, proceeding via an in situ generated iminium intermediate.

Synthesis of Levoglucosenone‐Based Amphiphilic Molecules via Microwave‐Assisted Michael Additions

Chemistry–Methods, Volume 6, Issue 6, June 2026.
Comparison between the conventional and the sustainable synthetic microwave‐based approach for Michael addition reactions on LGO developed in this work. Aligning with the objectives of the EU chemicals strategy for sustainability, an ultrarapid, safe and sustainable method for producing a library of levoglucosenone (LGO)‐based amphiphilic molecules was

Biodegradable Materials Composed of PLA and High Load Triglycerides

Macromolecular Materials and Engineering, Volume 311, Issue 6, June 2026.
Transparent films of polylactic acid (PLA) was prepared with high sesame oil load (50% w/w). The cross‐section analysis of the films indicate that the oils are not absorbed into the polymer matrix; rather, they are stored as small droplets within the film.

Transcriptomic analysis reveals the hepatic response mechanisms of the Chinese spiny frog (Quasipaa spinosa) to Citrobacter freundii infection

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract To elucidate the pathogen and host response mechanisms underlying mass mortality in Quasipaa spinosa, dominant bacteria were isolated from diseased individuals and identified as Citrobacter freundii by morphological, physiological, and biochemical characterization, 16S rRNA sequencing, and phylogenetic analysis.

Novel interactions between the C5‐C5aR1 Axis and IF1: Implications for kidney mitochondrial physiology and ischemia–reperfusion injury

Physiological Reports, Volume 14, Issue 11, June 2026.
Abstract Ischemia‐reperfusion injury (IRI) is a prevalent condition that predominantly afflicts hospitalized patients, inducing acute kidney injury (AKI). In recent years, complement 5 (C5) and its anaphylatoxin receptor C5aR1 have been implicated in driving kidney IRI and loss of function.
