Synthetic reactions driven by electron-donor?acceptor (EDA) complexes

期刊: BEILSTEIN JOURNAL OF ORGANIC CHEMISTRY, 2021; 17 ()

The reversible, weak ground-state aggregate formed by dipole?dipole interactions between an electron donor and an electron acceptor is referred to as ......

A novel methodology for the efficient synthesis of 3-monohalooxindoles by acidolysis of 3-phosphate-substituted oxindoles with haloid acids

期刊: BEILSTEIN JOURNAL OF ORGANIC CHEMISTRY, 2021; 17 ()

A novel method for the synthesis of 3-monohalooxindoles by acidolysis of isatin-derived 3-phosphate-substituted oxindoles with haloid acids was develo......

Copper-mediated oxidative C-H/N-H activations with alkynes by removable hydrazides

期刊: BEILSTEIN JOURNAL OF ORGANIC CHEMISTRY, 2021; 17 ()

The efficient copper-mediated oxidative C-H alkynylation of benzhydrazides was accomplished with terminal alkynes. Thus, a heteroaromatic removable N-......

期刊: BEILSTEIN JOURNAL OF ORGANIC CHEMISTRY, 2021; 17 ()

The treatment of 2-(2-vinylphenyl)acetaldehydes or 3-(2-vinylphenyl)propanals with BF3 center dot Et2O results in an intramolecular Prins reaction aff......

Heterogeneous photocatalytic cyanomethylarylation of alkenes with acetonitrile: synthesis of diverse nitrogenous heterocyclic compounds

期刊: BEILSTEIN JOURNAL OF ORGANIC CHEMISTRY, 2021; 17 ()

A visible light-mediated heterogeneous photocatalytic cyanomethylarylation of alkenes with acetonitrile has been established using K-modified carbon n......

A chromatography-free and aqueous waste-free process for thioamide preparation with Lawesson's reagent

期刊: BEILSTEIN JOURNAL OF ORGANIC CHEMISTRY, 2021; 17 ()

After completing the thio-substitution with Lawesson?s reagent, ethanol was found to be effective in the decomposition of the inherent stoichiometric ......

Metal-free visible-light-enabled vicinal trifluoromethyl dithiolation of unactivated alkenes

期刊: BEILSTEIN JOURNAL OF ORGANIC CHEMISTRY, 2021; 17 ()

The difunctionalization of alkenes involving a trifluoromethylthio group (SCF3) for the conversion of versatile and readily available olefins into str......

beta-Lactamase inhibition profile of new amidine-substituted diazabicyclooctanes

期刊: BEILSTEIN JOURNAL OF ORGANIC CHEMISTRY, 2021; 17 ()

The diazabicyclooctane (DBO) scaffold is the backbone of non-?-lactam-based second generation ?-lactamase inhibitors. As part of our efforts, we have ......

The fluorescence of a mercury probe based on osthol

期刊: BEILSTEIN JOURNAL OF ORGANIC CHEMISTRY, 2021; 17 ()

The ability of osthol (OST) to recognize mercury ions in aqueous solution was studied using fluorescence, UV-vis spectrophotometry, mass spectrometry,......

Circularly polarized luminescent systems fabricated by Troger's base derivatives through two different strategies

期刊: BEILSTEIN JOURNAL OF ORGANIC CHEMISTRY, 2021; 17 ()

The Troger's base derivative rac-TBPP was synthesized and separated into two enantiomers R-2N-TBPP and S-2N-TBPP by chiral column chromatography. Thes......

Insight into functionalized-macrocycles-guided supramolecular photocatalysis

期刊: BEILSTEIN JOURNAL OF ORGANIC CHEMISTRY, 2021; 17 ()

Due to the unique characteristics of macrocycles (e.g., the ease of modification, hydrophobic cavities, and specific guest recognition), they can prov......

Synthesis of trifluoromethyl ketones by nucleophilic trifluoromethylation of esters under a fluoroform/KHMDS/triglyme system
