Design and Utilization of Stable Hydrofluoroolefin‐Based Trifluoropropynyl Surrogate for Sonogashira Coupling

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A novel methodology for the construction of aromatic and heteroaromatic trifluoropropynyl derivatives has been developed. The new protocol is based on a tandem Sonogashira cross‐coupling reaction between a bench‐stable trifluoropropynyl carbinol reagent, generated from the commercially available and inexpensive hydrofluoroolefin‐1234yf gas, and (hetero)

Exploring the Uncharted Indolizine Chemical Space: Construction of 5‐Acylindolizines via a Domino Aldol–Vinylogous Aldol Process

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A domino aldol condensation–intramolecular vinylogous aldol condensation process was implemented for the first time to enable access to a wide range of novel 5‐acylated indolizines with a hydrogen, an alkyl, an aryl, or an alkoxy moiety at the C7 site.

Nb2CBr2 MXene Monolayer as a Novel Material: A First Principle Study

open access: yesAdvanced Theory and Simulations, EarlyView.
Illustration of the monolayer cell, cell replicated in directions a and b, graph of optical absorption and thermodynamic potentials as a function of temperature. Abstract Niobium‐based MXenes show promising properties and applications, but have not yet been sufficiently investigated, especially with halogen surface terminations. This study investigates

Protein Language Model‐Guided Engineering of a 2,3‐Butanediol Dehydrogenase for the Enantioselective Synthesis of Cyclic α‐Hydroxy Ketones

open access: yesAdvanced Science, EarlyView.
A (2R,3R)‐butanediol dehydrogenase from Bacillus subtilis (BsBDH) is engineered for the enantioselective synthesis of 2‐hydroxycyclohexanone. A PASS computational design strategy is proposed to enhance the thermostability of BsBDH. Moreover, ESM‐1v combined with ISM is utilized for enhancing and inverting its stereoselectivity.

Cinnamic‐Hydroxamic‐Acid Derivatives Exhibit Antibiotic, Anti‐Biofilm, and Supercoiling Relaxation Properties by Targeting Bacterial Nucleoid‐Associated Protein HU

open access: yesAdvanced Science, EarlyView.
Cinnamic‐hydroxamic‐acid derivatives (CHADs) are identified as novel inhibitors of the bacterial nucleoid‐associated protein HU, exhibiting potent antibacterial, anti‐biofilm (both inhibition and eradication), and DNA relaxation (anti‐supercoiling) activities. Moreover, CHADs demonstrate strong synergistic effects with multiple antibiotics.

Enhancing Cycling Stability of Aqueous Aluminum‐Metal Batteries via LaCl3‐Modulated Interfacial Reactions

open access: yesAdvanced Science, EarlyView.
In the aqueous AlCl3 electrolyte of aluminum‐metal batteries, the introduction of LaCl3 adjusts the solvation structure of Al3+ and enhances its diffusion level. The oxide precipitate formed by La3+ covers the aluminum metal anode and effectively alleviates corrosion reactions, thereby improving the cycling stability of the battery.

Assessment of the atmospheric impact of volcanic eruptions [PDF]

open access: yes
The dominant global impact of volcanic activity is likely to be related to the effects of volcanic gases on the Earth's atmosphere. Volcanic gas emissions from individual volcanic arc eruptions are likely to cause increases in the stratospheric optical ...
