Photochemistry of dibenzobarrelenes and [alpha]-adamantyl acetophenones in both the solution and crystalline state
… proposed maximum abstracting distance of 3.0 A. Pyrazinone 197 and pyrazinethione 199 were synthesized for the solid state [4 +4] photocycloaddition reactions. It was found that pyrazinone 197 gave high optical yield of the photoproduct 198 (95% e.e.); this result was discussed based on the …

PART I: SYNTHESIS OF PHENOLIC ANTIBACTERIALS AND NATURAL PRODUCTS PART II: RAPID ASSESSMENT OF HYDROGEN BONDING CAPACITY
… to measure hydrogen bonding capacity using a pyrazinone sensor. This colormetric sensor reversibly binds to a hydrogen bond donor, resulting in a blue shift as additional equivalents of donor are added. Titration with excess equivalents of donor is used to determine the binding coefficient, …

Untersuchungen zur Bildung von Furosin und N-terminalen 2(1H)-Pyrazinonen
… erfolgt. Die identifizierten N-terminalen 2(1H)-Pyrazinone weisen charakteristische UV-Absorptions- sowie Fluoreszenz-Spektren auf. Um die Reaktivität des N-Terminus und damit die Bedeutung der 2(1H)-Pyrazinon-Bildung beurteilen zu können, wurden vergleichende Studien mit dem als …
