Energy Harvesting from CO2 Emission Exploiting Ionic Liquid‐Based Electrochemical Capacitor

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The concept proposes energy harvesting from CO2 emissions using ionic liquids (IL)‐based supercapacitor. By alternating CO2 and N2 gasses during electrode charging/discharging, the energy from salinity gradients is captured. ILs absorb CO2, altering electrode/IL interactions and generating electrical energy. This method introduces for the first time an

Asymmetric Intramolecular α‐Arylation of Polar Amino Acids Bearing β‐Leaving Groups

open access: yesAngewandte Chemie, EarlyView.
Use of enolate chemistry to functionalise amino acids with β‐heteroatom side‐chains (serine, cysteine, threonine, etc.) is hampered by β‐elimination. We show that α‐arylation can be achieved by incorporating the side chain into a saturated heterocycle, making the unwanted elimination a disfavoured 5‐endo‐trig reaction.

Synthesis of (−)‐8a‐epi‐Lentiginosine via Tsuji–Trost Reaction of d‐Glucose‐Derived Allylic Alcohols and Crystal Structure Analysis

open access: yesAsian Journal of Organic Chemistry, EarlyView.
A facile synthetic route to (−)‐8a‐epi‐lentiginosine from d‐glucose using the Pd‐BiPhePhos catalyzed intramolecular Tsuji–Trost reaction of non−derivatized allylic alcohol as a key construction of the hydroxylated pyrrolidine ring is reported. The crystal structure of (−)‐8a‐epi‐lentiginosne showed the envelope conformation of the five‐membered ring ...

Total Synthesis of Isodaphlongamine H by Iridium‐Catalyzed Reductive [3 + 2] Cycloaddition of N‐Hydroxylactam

open access: yesAngewandte Chemie, EarlyView.
The total synthesis of isodaphlongamine H was accomplished by a lactam strategy. This strategy started with alkylation and N‐oxidation of a readily available chiral lactam. For the key functionalization of the amide carbonyl, an iridium‐catalyzed reductive [3 + 2] cycloaddition of the N‐hydroxylactam afforded the tricyclic isoxazolidine, which was ...

Enzymatic Kinetic Resolution of tert-Butyl 2-(1-Hydroxyethyl)phenylcarbamate, A Key Intermediate to Chiral Organoselenanes and Organotelluranes

open access: yesMolecules, 2011
The enzymatic kinetic resolution of tert-butyl 2-(1-hydroxyethyl) phenylcarbamate via lipase-catalyzed transesterification reaction was studied. We investigated several reaction conditions and the carbamate was resolved by Candida antarctica lipase B ...

Production Of 11C‐Labeled Amides Via “In‐Loop” 11C‐Carbonylation

open access: yesAsian Journal of Organic Chemistry, EarlyView.
The current work utilizes carbon‐11 labelled aroyl dimethylaminopyridinium salts in a two‐step in‐loop carbonylative cross‐coupling reaction of aryl halides with [¹¹C]CO yielding a diverse range of carbon‐11 labelled primary benzamides with good to excellent yields.

POTENTIAL FARM-LEVEL IMPACTS OF PROPOSED FQPA IMPLEMENTATION: THE TENNESSEE CASE [PDF]

open access: yes
This research estimates farm-level impacts of a potential ban on organophosphates and carbamates under the FQPA. Insecticide expenditure and first- and fifth-year yield impacts are estimated for five Tennessee representative farms.

Metronidazole and Secnidazole Carbamates: Synthesis, Antiprotozoal Activity, and Molecular Dynamics Studies

open access: yesMolecules, 2020
We prepared a series of 10 carbamates derivatives based on two common antiprotozoal drugs: metronidazole (1−5) and secnidazole (6−10). The compounds were tested in vitro against a set of two amitochondriate protozoa: Giardia duodenalis and ...

Animal models of lung cancer: Phenotypic comparison of different animal models of lung cancer and their application in the study of mechanisms

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Grafts used to construct lung cancer animal models come from various sources, primarily cell lines, patient‐derived tumor tissues, and circulating tumor cells. Based on the sources of grafts and research objectives, lung cancer animal models can be categorized into several types: chemical‐induced models, orthotopic transplantation models, heterotopic ...
