Optimized geometries of NH-equatorial and NH-axial conformers of 5H-dibenz[b,f]azepine and CH-equatorial and CH-axial conformers of 5H-dibenzo[a,d]cyclohepten-5-ol have been obtained at the B3LYP and BLYP levels of the hybrid density functional theory with the 6-31G* and 6-31+G* basis sets. Corresponding ab initio calculations have also been performed at the HF/6-31G* level. For the investigated levels harmonic vibrational frequencies were calculated analytically. FT Raman (3200-200 cm-1) and infrared (3900-400 cm-1) spectra of 5H-dibenz[b,f]azepine and 5H-dibenzo[a,d]cyclohepten-5-ol have been recorded in the solid state and interpreted on a base of theoretical predictions.

In this work, a series of novel substituted polycyclic pyridone derivatives were designed and synthesized as potent anti-influenza agents. The cytopathic effect (CPE) assay and cytotoxicity assay indicated that all of the compounds possessed potent anti-influenza virus activity and relatively low cytotoxicity; some of them inhibited the replication of influenza A virus (IAV) at picomolar concentrations. Further studies revealed that, at a concentration of 3 nM, three compounds (10a, 10d, and 10g) could significantly reduce the M2 RNA amounts and M2 protein expression of IAV and inhibit the activity of RNA-dependent RNA polymerase (RdRp). Among them, (R)-12-(5H-dibenzo[a,d][7]annulen-5-yl)-7-hydroxy-3,4,12,12a-tetrahydro-1H-[1,4]oxazino[3,4-c]pyrido[2,1-f][1,2,4]triazine-6,8-dione (10a) was found to be a promising anti-influenza drug candidate with good human liver microsomal stability, as well as with better selectivity index and oral bioavailability than Baloxavir.

The pyrolysis of 10,11-dihydro-5H-dibenzo[a,d]cicloheptadien-5-ol (4) and of 5H-dibenzo[a,d]cycloheptatrien-5-ol (5) in flowvacuum conditions (advanced vacuum, inert atmosphere) on zeolites at 300°C is presented. The reaction products were identified by GC/MS using authentic samples and a reaction mechanisms involving cationic species as intermediates were proposed. A comparison with the pyrolysis of the same compounds performed in FVP conditions on quartz is presented.
