Previously disclosed C6 amido and benzimidazole dihydropyrazolopyrimidines were potent and selective blockers of IKur current. Syntheses and SAR for C6 triazolo and imidazo dihydropyrazolopyrimidines series are described. Trifluoromethylcyclohexyl N(1) triazole, compound 51, was identified as a potent and selective Kv1.5 inhibitor with an acceptable PK and liability profile.
2-Pyridylnitrene-1,3-diazacyclohepta-1,2,4,6-tetraene rearrangements in the trifluoromethyl-2-pyridyl azide series

Photolysis of Ar matrix isolated trifluoromethyl-substituted 2-pyridyl azides/tetrazolo[1,5-a]pyridines at 12-18 K causes rapid and mostly clean conversion to the corresponding 1,3-diazacyclohepta-1,2,4,6-tetraenes (4D, 5D, 5,6D, and 4,6D) absorbing near 2000 cm-1 in the IR. In the latter case, the intermediate 3,5-bis(trifluoromethyl)-2-pyridylnitrene (4,6N) was observed by both ESR and IR spectroscopy and converted to the diazacycloheptatetraene 4,6D in the course of 90 min of UV irradiation. The 2-pyridylnitrenes were generally observable by ESR spectroscopy (D/hc ~ 1.05-1.10; E/hc ~ 0.0 cm-1) following both photochemical and thermal (FVP) generation from the 2-azidopyridines. Irradiation of the Ar matrix isolated mixtures of nitrenes and diazacycloheptatetraenes also caused development of weak carbene transitions (D/hc ~ 0.40-0.45; E/hc ~ 0.006 cm-1) in the ESR spectra.
Trifluoromethyl-substituted Dehydrodiazepines and Cyanopyrroles from Azido-/Tetrazolo-pyridines

1,2-Didehydro-1,3-diazepines 4D, 5D, 4,6D and 5,6D are identified as unique products of both photolysis and thermolysis of azido-/tetrazolo-pyridines; the ultimate thermolysis products are trifluoromethylpyrrolecarbonitriles (7-9, 11-13 and 16-18).

Pyridine ring substituted (1H-1,2,3-triazol-1-yl)pyridines were prepared and found to have insecticidal utility. 2-Chloro-6-(1H-1,2,3-triazol-1-yl)pyridine, for example, was prepared from 2-azio-6-chloropyridine and methyl propiolate by sequential condensation, hydrolysis, and decarboxylation and found to control aster leafhoppers.
