Hydrogenation of 9-pyridylmethylene(aza)fluorenes and 9-benzylidene-4-azafluorene at 250 degrees C and p(H2) = 130 atm in the presence of Re2S7 as a catalyst occurs preferably at the exocyclic double bond of the fulvene fragment to yield pyridyl-9-(aza)fluorenylmethanes.

The synthesis and characterization of a novel family of positively charged fac-[Re(bpy)(CO)(3)(L)]PF6 (bpy = 2,2'-bipyridine) complexes are reported, where L is a pyridine functionalized in para or meta position with a fulvene moiety, namely, 4-fluoren-9-ylidenemethyl-pyridine (pFpy) and 3-fluoren-9-ylidenemethyl-pyridine (mFpy). The complexes were prepared in high yield (86%) by direct addition at room temperature of the corresponding pyridine to the tetrahydrofuran (THF) adduct fac-[Re(bpy)(CO)(3)(THF)][PF6] precursor. Both ligand and complex structures were fully characterized by a variety of techniques including X-ray crystallography. The complexes did not exhibit the expected triplet mixed metal ligand-to-ligand charge transfer (MLLCT) emission, because of its deactivation by the non-emissive triplet excited state of fulvene. The absorption profile shows that the MLLCT is overshadowed by the fulvene centered pi-pi* transition of higher molar absorptivity as shown by time dependent density functional theory (TD-DFT) calculations. The position of the fulvene on the pyridyl ring has a large effect on this transition, the para position displaying a much higher absorption coefficient (21.3 x 10(3) M-1 cm(-1)) at lower energy (364 nm) than the meta position (331 nm, 16.0 x 10(3) M-1 cm(-1))

Elevated aldosterone levels are key effectors for the development and progression of congestive heart failure and myocardial fibrosis. Recently, we proposed inhibition of aldosteronesynthase (CYP11B2) as an innovative strategy for the treatment of these diseases. In this study, the synthesis and biological evaluation of E- and Z-(pyridylmethylene)tetrahydronaphthalenes and -indanes (1a,b-38a) is described
