Abstract BINOLs are valuable and widely used building blocks, chiral ligands, catalysts that effective across a remarkable range of different chemical transformations. Here we demonstrate an ammonium salt catalyzed kinetic resolution racemic with benzyl tosylate proceeds s up to 46. This is scalable practical process can be applied >30 C 2 ‐ non‐ ‐symmetric BINOLs. Implementation this method enables the enantioselective synthesis wide BINOL derivatives over 99:1 e.r.
Abstract Das erste Gesetz der Photochemie, das auf Theodor von Grotthuß und John W. Draper zurückgeht, besagt, dass nur Teil des Lichts, durch Materie absorbiert wird, eine Wirkung hervorruft. Entsprechend lässt sich Reaktionsverhalten einer chemischen Verbindung steuern, wenn ihr Absorptionsverhalten Emission Lichtquelle angepasst wird. Eine chemische mit einem Chromophor, bei niedrigen Wellenlänge Licht absorbiert, wird langwellige Strahlung nicht angeregt. Gelingt es reversible...
Abstract An approach to the intramolecular Diels–Alder reaction has led a cascade synthesis of complex carbocycles composed three fused rings and up five stereocenters with complete stereocontrol. Computational analysis reveals that proceeds by Michael/Michael/cyclopropanation/epimerization in which size coordination counterion is key.

The conversion of large files catalogue information requires, in addition to the manpower for keypunching, a considerable amount preediting by professional staff. An experiment machine editing and tagging unedited but structured demonstrated possibility eliminating effort from majority records.

Abstract The National Research Data Infrastructure for Chemistry (NFDI4Chem) has been providing a lot of useful resources and support chemists two years now.
In this manuscript, we examine the role of errors in data-driven research and assess extent to which issue has been addressed across various fields. It presents examples how scientific communities have related problems highlights observations on newly developed error cultures can positively impact process. We do against backdrop Germany’s effort facilitate data sharing through a National Research Data Infrastructure (NFDI) was initiated 2018. demonstrate, both benefit from suitable...
In der Struktur des vorgeschlagenen Übergangszustands 47 in Abbildung 1 dieser Zuschrift ist Katalysator falsch gezeichnet. Eine korrigierte Fassung daher hier gezeigt. Proposed mechanism of observed kinetic resolution. Die Autoren bitten um Entschuldigung für diesen Fehler, keinerlei Auswirkungen auf die Schlussfolgerungen hat.
