Stereoselective intermolecular radical cascade reactions of tryptophans or ɤ-alkenyl-α-amino acids with acrylamides via photoredox catalysis

Nature Communications, 2022
Photocatalytic radical cascade reactions enable the facile construction of diverse cyclic compounds, though they rely on templated precursors. In this paper, the authors report on stereoselective intermolecular radical cascade reaction between tryptophan

Living supramolecular polymerization of fluorinated cyclohexanes

Nature Communications, 2021
Living supramolecular polymerization can produce precise covalent polymers, but the scope of monomers is still narrow. Here the authors show a molecular platform for living supramolecular polymerization that is based on the unique structure of all-cis 1 ...

Oral preanesthetic medication in children ... comparison between midazolam alone and in combination with ketamine: a systematic review and meta-analysis

Brazilian Journal of Anesthesiology, 2023
Background: Up to 60% of pediatric surgical patients develop high levels of preoperative anxiety. This study compared the effects of oral combinations of midazolam and ketamine with oral midazolam alone for pediatric preanesthetic medication.

Trisubstituted Cyclohexanes / Trisubstituted Cyclohexanes

Zeitschrift für Naturforschung B, 1985
C-Tertiarv vinylketones or the corresponding masked vinylketone derivatives react with pyrrolidin-2-one in the system sodium hydride.dimethylsulfoxide to substituted cyclohexanes of the 1,3.5- and sometimes additionally of the 1,2.4-type. Only acetophenone Mannich bases bear­ing a p-hydroxy or a dimethylamino group failed in cyclization.

Novel Ring Systems: Spiro[Cycloalkane] Derivatives of Triazolo- and Tetrazolo-Pyridazines

Molecules, 2021
In orderto synthesize new pyridazine derivatives anellated with different nitrogen heterocyclic moieties, spiro[cycloalkane]pyridazinones were transformed into the corresponding thioxo derivatives via a reaction with phosphorus pentasulfide. The reaction

Volatile hydrocarbons from endophytic fungi and their efficacy in fuel production and disease control

Egyptian Journal of Biological Pest Control, 2018
Endophytic fungi are the microorganisms which asymptomatically colonize internal tissues of plant roots and shoots. Endophytes produce a broad spectrum of odorous compounds with different physicochemical and biological properties that make them useful in
