Site-Selective, Photocatalytic Vinylogous Amidation of Enones
(American Chemical Society, 2022)Despite the broad interest in organic compounds possessing a γ-aminocarbonyl motif, limited strategies for their synthesis have been reported. Herein, we describe a mild and efficient method for the site-selective amidation ... -
Multifunctional Heteropentalenes: From Synthesis to Optoelectronic Applications
(American Chemical Society, 2022)In the broad family of heteropentalenes, the combination of two five-membered heterocyclic rings fused in the [3,2-b] mode has attracted the most significant attention. The relatively straightforward access to these ... -
Simultaneous Enantiodivergent Synthesis of Diverse Lactones and Lactams via Sequential One-Pot Enzymatic Kinetic Resolution–Ring-Closing Metathesis Reactions
(MDPI, 2022)One of the goals of diversity-oriented synthesis is to achieve the structural diversity of obtained compounds. As most biologically active compounds are chiral, it is important to develop enantioselective methods of their ... -
On-Surface Azide–Alkyne Cycloaddition Reaction: Does It Click with Ruthenium Catalysts?
(American Chemical Society, 2022)Owing to its simplicity, selectivity, high yield, and the absence of byproducts, the “click” azide–alkyne reaction is widely used in many areas. The reaction is usually catalyzed by copper(I), which selectively produces ... -
NHC–BIAN–Cu(I)-Catalyzed Friedländer-Type Annulation of 2-Amino-3-(per)fluoroacetylpyridines with Alkynes on Water
(American Chemical Society, 2022)The direct catalytic alkynylation/dehydrative cyclization of 2-amino-3-trifluoroacetyl-pyridines on water was developed for the efficient synthesis of a broad range of fluorinated 1,8-naphthyridines from terminal alkynes. ... -
Modular Nitrogen-Doped Concave Polycyclic Aromatic Hydrocarbons for High-Performance Organic Light-Emitting Diodes with Tunable Emission Mechanisms
(Wiley, 2022)Although bowl-shaped N-pyrrolic polycyclic aromatic hydrocarbons (PAHs) can achieve excellent electron-donating ability, their application for optoelectronics is hampered by typically low photoluminescence quantum yields ... -
Wheat germ lipase: isolation, purification and applications
(Taylor and Francis, 2022)In recent years, wheat germ lipase (WGL) is attracting considerable interest. To date, several WGL applications have already been described: (i) fats and oils modification; (ii) esterification reactions in organic media, ... -
Recognition-Induced Enhanced Emission of Core-Fluorescent ESIPT-type Macrocycles
(Wiley, 2022)Core-fluorescent cavitandsbased on 2-(2′-resorcinol)benzimidazole fluorophores (RBIs)merged with the resorcin[4]arene skeleton were designed and synthesized. The cavitands, due to the presence of intramolecular ... -
Promiscuous Lipase-Catalyzed Knoevenagel–Phospha–Michael Reaction for the Synthesis of Antimicrobial β-Phosphono Malonates
(MDPI, 2022)An enzymatic route for phosphorous–carbon bond formation was developed by discovering new promiscuous activity of lipase. We reported a new metal-free biocatalytic method for the synthesis of pharmacologically relevant ... -
Intensification of Double Kinetic Resolution of Chiral Amines and Alcohols via Chemoselective Formation of a Carbonate–Enzyme Intermediate
(MDPI, 2022)Chiral amines and alcohols are synthons of numerous pharmaceutically-relevant compounds. The previously developed enzymatic kinetic resolution approaches utilize a chiral racemic molecule and achiral acyl donor (or acyl ... -
Reductive Elimination from Sterically Encumbered Ni−Polypyridine Complexes
(American Chemical Society, 2022)Herein we disclose the synthesis of sterically encumbered dialkylnickel(II) complexes bearing 2,9-dimethyl-1,10-phenanthroline ligands. A comparison with their unsubstituted analogues by both X-ray crystallography and ... -
Network search algorithms and scoring functionsfor advanced-level computerized synthesis planning
(Wiley, 2022)In 2020, a“hybrid”expert-AI computer program called Chematica (a.k.a. Synthia)was shown to autonomously plan multistep syntheses of complex natural prod-ucts, which remain outside the reach of purely data-driven AI programs. ... -
On-off-on Control of Molecular Inversion Symmetry via Multi-stage Protonation: Elucidating Vibronic Laporte Rule
(Wiley, 2022)The Laporte rule dictates that one- and two-photon absorption spectra of inversion-symmetric molecules should display alternatively forbidden electronic transitions; however, for organic fluorophores, drawing clear distinction ... -
Tandem rigidification and p-extension as a key tool for the development of a narrow linewidth yellow hyperfluorescent OLED system
(Royal Society of Chemistry, 2022)Hyperfluorescence (HF), a relatively new phenomenon utilizing the transfer of excitons between two luminophores, requires careful pairwise tuning of molecular energy levels and is proposed to be the crucial step towards ... -
