The preparation of a number of B-aminogl~-oxaIine hydrochlorides containing part of the %substituted ethylamine structure in the hetero-ring is described. -4 novel application of the Mannich reaction to the glyoxaline ring is also described, and a discussion on ultra-violet absorption spectra of the 5-aminoglyoxalines is given. The compounds are to be tested for sympathomimetic activity.WITH the exception of the carbonic acid derivatives for which " pressor effects " have been claimed (Fastier, Nature, 1944, IS, 429), compounds endowed with a true adrenergic or sympathomimetic action all appear to possess a stronglv basic character and the fundamental structure (I) where R is an alkyl, aromatic, or heterocyclic radical.
DIE ANALYSE DES Fortbildungsverhaltens und der Fortbildungswünsche von Chemielehrerinnen und ‐lehrern war Gegenstand einer im Jahr 2002 durchgeführten und vom Fonds der Chemischen Industrie geförderten empirischen Untersuchung der drei Chemielehrerfortbildungszentren Braunschweig, Dortmund und Frankfurt. In diesem Artikel werden die zentralen Ergebnisse der mittels Fragebögen und Interviews erhobenen Daten von über 2.000 Chemielehrerinnen und ‐ lehrern vorgestellt.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
