Abstract
A series of differently substituted 2,4-diaryl-3-azabicyclo[3.3.1]nonan-9-one oximes have been synthesized and their 1H and 13C NMR chemical shifts have been unambiguously assigned using H,H-COSY, NOESY, HSQC, and HMBC spectral data. On the basis of the NMR studies, irrespective of the nature and position of the substituents, all reported compounds exist in twin-chair conformation with equatorial disposition of the phenyl groups at C-2 and C-4 of the 3-azabicyclononane moiety. Among the synthesized oxime derivatives, compounds with halo-substituents at ortho/para positions of the phenyl showed good antifungal profile against all tested organisms.
