New series of 2,4-diaryl-3-azabicyclo[3.3.1]nonan-9-one 4'-phenylthiosemicarbazones (compounds 9-16) was obtained from the corresponding 2,4-diaryl-3-azabicyclo[3.3.1]nonan-9-ones. The synthesized compounds have been characterized by their elemental, analytical, and spectral studies. Besides, these reported compounds were screened for their antibacterial and antifungal activities against a spectrum

cyclization of 2,4-diaryl-3-azabicyclo[3.3.1]nonan-9-one thiosemicarbazones (2a–2h, 3a and 3b) with acetic anhydride/propionic anhydride and were characterized by Elemental analysis, IR, 1H NMR and 13C NMR spectral analysis. Single crystal X-ray diffraction has also been recorded for compounds 4c and 5a. From the NMR and Single crystal X-ray diffraction analysis, compounds 4b–4d, 4f–4h, 5b, 5c, 5f–5h, 6a

-diaryl-3-azabicyclo[3.3.1]nonan-9-ones ( 1–7 ) reaction with pyrazine-2-carbohydrazide. The stereochemistry of the newly synthesized compounds were unambiguously assigned using FT-IR, 1 H, 13 C, and 2D (COSY, HSQC, HMBC, ROESY) nuclear magnetic resonance (NMR) spectral data. The chemical shifts suggest that all these compounds adopt twin-chair conformation with equatorial orientation of aryl substitutions in solution

[3.3.1]nonan-9-ylidene)hydrazinyl)-4-oxo-4H-1,3-thiazine-6-carboxylates (1-6). In order to investigate the antitumoractivities of the synthesized compounds, in vitro cytotoxicity studies were carried out using human prostate cancer cell lines. Tested compounds showed good/moderate activities against cancer cell lines and further investigation carried out by live/dead assay. Graphical Abstract
exploit the potential antimicrobial activities of azabicyclic skeleton based compounds, a set of 2r,4c-diaryl-3-azabicyclo[3.3.1]nonan-9-one-4-methyl-1,2,3-thiadazole-5-carbonyl hydrazones were synthesized. Unambiguous structural elucidation has been carried out by investigating IR, H1, C13 NMR, and elemental analysis. 2DNMRspectra (1H–1H COSY, HSQC, HMBC, and NOESY) were recorded for a representative
