Quantifying the Electrophilicity of 9(10H)‐Phenanthrenone‐ and 1‐Acenaphthenone‐Derived α, β‐Unsaturated Ketones

open access: yesJournal of Physical Organic Chemistry, Volume 39, Issue 2, February 2026.
The electrophilicities (Mayr E) of the α, β‐unsaturated ketones A and B were determined by kinetic studies of their reactions with carbanions (reference nucleophiles) in DMSO at 20°C. The different reactivities of A and B were rationalized by DFT calculations.

Spirosilanes Activate Gold(I)‐Catalysts in Cycloisomerization and Intermolecular Reactions

open access: yesAngewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Spirosilanes activate LAuCl complexes to promote catalysis. This silver‐free activation through weak interactions is nondestructive so that low loadings of LAuCl are possible as well as their recycling. It can also be beneficial for asymmetric catalysis.

Exploring the role of the α-carboxyphosphonate moiety in the HIV-RT activity of α-carboxy nucleoside phosphonates [PDF]

open access: yes, 2016
As α-carboxy nucleoside phosphonates (α-CNPs) have demonstrated a novel mode of action of HIV-1 reverse transcriptase inhibition, structurally related derivatives were synthesized, namely the malonate 2, the unsaturated and saturated bisphosphonates 3 ...

Palladium-Catalyzed α-Arylation of Dimethyl Malonate and Ethyl Cyanoacetate with o-Alkoxybromobenzenes for the Synthesis of Phenylacetic Acid, Esters and Phenylacetonitriles

open access: yesSynOpen, 2017
α-Aryl malonate and α-aryl cyano acetate moieties are found in the structures of many bioactive compounds. They are also key intermediates for the synthesis of many compounds such as isoflavonoids.

Neotetrazolium salt (NT) as an electron acceptor in living cell: a study on the JTC-3 and HeLa cells in culture [PDF]

open access: yes, 1965
1. By using a monolayer of tissue culture cells, JTC-3, JTC-3', JTC-3" and HeLa cells, the assays of neotetrazolium (NT) reduction at the cell level have been conducted on the cells without detaching the cells from the culture glass vessel wall.

Syn and anti conformers of diammonium aquabis(malonato)oxidovanadate(IV) in an anhydrate crystal

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2018
The asymmetric unit of the title anhydrate compound, (NH4)2[VO(C3H2O4)2(H2O)], consists of two independent complex anions and four ammonium cations. In the complex anions, the VIV atoms are each coordinated by two malonate ligands, one water molecule and

Adsorption and desorption dynamics of citric acid anions in soil [PDF]

open access: yes, 2010
The functional role of organic acid anions (e.g. citrate, oxalate, malonate, etc) in soil has been intensively investigated with special focus either on (i) microbial respiration and soil carbon dynamics, (ii) nutrient solubilization, or (iii) metal ...

Pseudotetraivprolides from Pseudomonas entomophila Provide Insights into the Biosynthesis of Detoxin/Rimosamide‐Like Anti‐Antibiotics

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 4, 22 January 2026.
Pseudotetraivprolide is a new player among the Detoxin/Rimosamide‐like natural products! Its biosynthesis requires FabD from primary metabolism and a PipDFG complex for final‐step acetylation – unlocking its anti‐antibotic activity. Abstract Novel variants of known natural product (NP) classes can provide valuable insights into their biosynthesis ...
