Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this book are presented the results from research on alternative approaches towards the synthesis of 4- aryl-l,2,3,4-tetrhydroisoquinolines as synthetic analogues of the alkaloid cherylline. Optimal conditions for the synthesis of the required 2,2-disubstituted ethylamine precursors are found. The Schotten- Baumann method for amide synthesis is then successfully applied and the synthesized amides are used in an intramolecular -amidoalkylation reaction to obtain 4-substituted 1,2,3,4-tetrahydroisoquinolines. An eco-friendly procedure utilizing PPA/SiO2 catalyst for the intramolecular -amidoalkylation is developed. Microwave-assisted variant of this eco-friendly procedure is also successfully developed. By the Bischler-Napieralski method are synthesized five new 1,4- disubstituted-l,2,3,4-tetrahydroisoquinolines. These are potential inhibitors of DHODH. It is found that the reduction of 1,4-disubstituted 3,4-dihydroisoquinolines leads to formation of diastereoisomers. The diastereoisomers are successfully separated by preparative column chromatography and 2:1 (cis:trans) ratio is determined. This ratio is not affected by the temperature at which the reaction is carried out. 52 pp. Englisch.…
