Characterization and Optimization of the Alkaline Hydrolysis of Polyacrylonitrile Membranes
(MDPI, 2019-11-08)
There is currently an increasing interest in the development of polyacrylonitrile (PAN)-based membranes with new and enhanced properties which are of special importance in the processes of pervaporation, purification, and ...
Poly(l-lactide)-Based Anti-Inflammatory Responsive Surfaces for Surgical Implants
(MDPI, 2020-12-24)
In the last few decades, surgical implants have been widely used to restore the function of damaged bones or joints. However, it is essential to receive antibiotic or anti-inflammatory treatment to circumvent significant ...
Polycarbazole and Its Derivatives: Synthesis and Applications. A Review of the Last 10 Years
(MDPI, 2020-09-28)
Polycarbazole and its derivatives have been extensively used for the last three decades, although the interest in these materials briefly decreased. However, the increasing demand for conductive polymers for several ...
Naphthyl-Containing Organophosphonate Derivatives of Keggin-Type Polyoxotungstates
(MDPI, 2016-06)
New organophosphonate derivatives of monovacant Keggin-type polyoxotungstates that contain naphthyl groups have been synthesized and characterized in both solid state and solution. Single-crystal structural analysis shows ...
syn-Selective Michael reaction of α-branched aryl acetaldehydes with nitroolefins promoted by squaric amino acid derived bifunctional Brønsted bases
(Wiley, 2021-07-07)
[EN] Here we describe a direct access to 2,2,3-trisubstituted syn γ-nitroaldehydes by addition of α-branched aryl acetaldehydes to
nitroolefins promoted by a cinchona based squaric acid-derived
amino acid peptide. Different ...
Recent Advances in Homogeneous Metal-Catalyzed Aerobic C–H Oxidation of Benzylic Compounds
(MDPI, 2018-12-08)
Csp(3)-H oxidation of benzylic methylene compounds is an established strategy for the synthesis of aromatic ketones, esters, and amides. The need for more sustainable oxidizers has encouraged researchers to explore the use ...
Intramolecular Palladium(II)-catalyzed 6-endo C-H alkenylation directed by the remote N-protecting group. Mechanistic insight and application to the synthesis of dihydroquinolines
(American Chemical Society, 2019-12-30)
A protocol for the Pd(II)-catalyzed C-H alkenylation reaction of substituted N-allylanilines
via an unusual 6-endo process has been developed. A DFT study of the mechanistic pathway has shown
that the coordination of the ...
Pd(II)-Catalyzed C-H Acylation of (Hetero)arenes. Recent Advances
(MDPI, 2020-07-16)
Di(hetero)aryl ketones are important motifs present in natural products, pharmaceuticals or agrochemicals. In recent years, Pd(II)-catalyzed acylation of (hetero)arenes in the presence of an oxidant has emerged as a catalytic ...
Perturbation-Theory and Machine Learning (PTML). Model for High-Throughput Screening of Parham Reactions: Experimental and Theoretical Studies
(American Chemical Society, 2018-06-13)
Machine Learning (ML) algorithms are gaining importance in the processing of chemical information and modelling of chemical reactivity problems. In this work, we have developed a PTML model combining Perturbation-Theory ...
Molecular docking, SAR analysis and biophysical approaches in the study of the antibacterial activity of ceramides isolated from Cissus incisa
(Elsevier, 2021-02-18)
The developing of antibacterial resistance is becoming in crisis. In this sense, natural
products play a fundamental role in the discovery of antibacterial agents with diverse
mechanisms of action. Phytochemical investigation ...
