Synthesis and antifungal activity of novel aza-d--homosteroids, hydroisoquinolines, pyridines and dihydropyridines
摘要:
A series of novel aza-D-homosteroids and their hydroisoquinoline precursors were synthesized and tested for antifungal activity against a variety of Candida strains and also Aspergillus species. A number of 4-substituted pyridines and tetrahydropyridines were also tested. Several compounds showed a broad spectrum of modest antifungal activity and three structures were investigated further for fungicidal and in vivo activity.
Intramolekulare Aromatenalkylierungen, 18. Mitt. Synthese von 3,4-Dihydro-1′-methylspiro[naphthalin-1(2H), 4′-piperidinen]
摘要:
AbstractAus den Tetrahydropyridinen 10 entstehen in siedender Bromwasserstoffsäure stereoselektiv die Titelverbindungen 12, deren Struktur und Konfiguration durch NMR‐Spektroskopie und Röntgenstrukturanalyse bewiesen wird. Die Vorstufen 10 werden aus den Pyridincarbonitrilen 5 und den Grignardreagenzien 6 nach Standardverfahren gewonnen.
