A chiral Brønsted acid catalyzed dehydrogenative kinetic resolution of tetrahydroquinoline derivatives, which are representative of cyclic secondary amines, based on their hydrogen transfer to aromatic imines was efficiently achieved with high enantioselectivities. This hydrogen transfer of tetrahydroquinolines to imines was not driven by their… (More)
We demonstrate the basic features and advantages of Automated Argument System based on Logic of Multiple-Valued Argumentation by applying it to three convincing arguments: (i) Argument-based recommender system, (ii) Schedule management system and (iii) An integrated system of semantic web reasoning and argument-based reasoning.
The chiral phosphoric acid catalyzed enantioselective transfer hydrogenation of various ketimines was achieved by the use of 2-aryl indoline as the hydrogen donor. Corresponding chiral amines were obtained in good chemical yields with excellent enantioselectivities.
