Aqua(2,2′-bipyridine-κ2N,N′)[2-(3-thienyl)malonato-κ2O,O′]zinc(II) dihydrate

open access: yesActa Crystallographica Section E, 2009
In the crystal structure of the title compound, [Zn(C7H4O4S)(C10H8N2)(H2O)]·2H2O, the ZnII ion assumes a trigonal–bipyramidal coordination geometry completed by two N atoms from a 2,2′-bipyridine ligand, two O atoms from a 2-(

Design eines aus der Fettsäuresynthase der Maus abgeleiteten Multienzyms für die kompartimentierte chemo‐enzymatische Synthese von 2‐Pyron‐Polyketiden

open access: yesAngewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Die 4‐Cumarate‐Ligase (4CL1) aus Piper methysticum wurde mit einer nicht‐reduzierenden murinen Fettsäuresynthase verknüpft. Eine direkte Acylierung des ACP durch 4CL1 wurde beobachtet. Die Ketosynthase (KS) wurde so verändert, dass sie das nicht‐kanonische Zimtsäure‐Substrat akzeptiert.

Design of a Multienzyme Derived from Mouse Fatty Acid Synthase for the Compartmentalized Production of 2‐Pyrone Polyketides

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.
A multienzyme was formed and evaluated by covalently linking 4‐coumarate ligase (4CL1) from Piper methysticum to a non‐reducing murine fatty acid synthase. 4CL1 acylates the acyl carrier protein (ACP). The ketosynthase (KS) was engineered to accept the non‐native cinnamoyl substrate, which is elongated by malonyl‐CoA loaded via the malonyl‐acetyl ...

Diethyl 2-(2-nitrobenzylidene)malonate

open access: yesActa Crystallographica Section E, 2009
In the title compound, C14H15NO6, the ethoxycarbonyl groups adopt extended conformations. In the crystal, molecules are linked into centrosymmetric dimers via pairs of C—H...O hydrogen bonds with a R22(20) motif.

Unnatural α-amino ethyl esters from diethyl malonate or ethyl β-bromo-α-hydroxyiminocarboxylate

open access: yesBeilstein Journal of Organic Chemistry, 2018
We have explored here the scope of the age-old diethyl malonate-based accesses to α-amino esters involving Knoevenagel condensations of diethyl malonate on aldehydes, reductions of the resulting alkylidenemalonates, the preparation of the corresponding α-

Synergistic Roles of FAHD‐1 and PYC‐1 in Mitochondrial Function, Behavior, and Longevity in C. elegans

open access: yesAdvanced Biology, Volume 10, Issue 1, January 2026.
FAHD‐1 and PYC‐1 catalyze opposing mitochondrial reactions that regulate oxaloacetate homeostasis in Caenorhabditis elegans. Using single and double knockouts, this study reveals that both enzymes shape locomotion, reproduction, respiration, and lifespan.

An Efficient CO2‐Upcycling Platform Based on Engineered Halomonas TD with Enhanced Acetate‐Utilizing Capacity via Adaptive Laboratory Evolution

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
An electrochemical system is designed to convert CO2 into CO2‐derived electrolytes (CDE), mainly containing acetate and formate. The underlying mechanism of acetate metabolism in Halomonas TD80 is explored via ALE. Engineered TD80 produced high‐yield diversified products from CDE.

The Chemistry of Subphthalocyanines: Synthetic Strategies for their Axial, Peripheral, and Remote Postfunctionalization

open access: yesChemistryEurope, Volume 4, Issue 1, January 2026.
From axial and peripheral reactivity to remote derivatization, the chemical versatility of subphthalocyanines (SubPcs) renders them ideal scaffolds for the design of advanced functional materials. This review assembles the synthetic toolbox, key reaction conditions, and future challenges in SubPc functionalization, guiding the development of next ...

Preparation of diethyl malonate adducts from chalcone analogs containing a thienyl ring

open access: yesBulletin of the Chemical Society of Ethiopia, 2010
Nine chalcone-diethyl malonate derivatives (4a-i) were prepared by the reaction of chalcone derivatives (3a-i) with diethyl malonate in the presence of a catalytic amount of KOt-Bu in CH2CI2 in good to excellent yields. The products were characterized by
