Visible Light Photocatalysis of 6π Heterocyclization
Photo-mediated 6π cyclization is a valuable method for the formation of fused heterocyclic systems. Here we demonstrate that irradiation of cyclic 2-aryloxyketones with blue LED light in the presence of an IrIII complex leads to efficient and high yielding arylation across a panoply of substrates by energy transfer. 2-Arylthioketones and 2-arylaminoketones also cyclize effectively under these c...

15 صفحه اولBehavior of free sugar thiosemicarbazones toward heterocyclization reactions.
The heterocyclization reaction on thiosemicarbazones having the D-galacto, D-gluco and D-manno configuration was studied. We applied two different acetylating conditions, and the reaction products obtained were identified, spectroscopically characterized, and conformationally analyzed. Using experimental data, we discuss a possible mechanistic pathway for heterocyclization and evaluate the infl...
متن کاملRadiation Anisotropy Induced by Cosmic Strings 12
We report on a current investigation of the anisotropy pattern induced by cosmic strings on the cosmic microwave background radiation (MBR). We have numerically evolved a network of cosmic strings from a redshift of Z = 100 to the present and calculated the anisotropies which they induce. Based on a limited number of realizations, we have compared the results of our simulations with the observa...
متن کاملIL-12 attenuates bleomycin-induced pulmonary fibrosis.
Interleukin (IL)-12 is a potent inducer of interferon (IFN)-gamma. We postulated that IL-12 would attenuate bleomycin-induced pulmonary fibrosis. To test this hypothesis, we administered IL-12 or murine serum albumin to bleomycin-treated mice by daily intraperitoneal injection until day 12. Mice treated with IL-12 demonstrated decreased hydroxyproline levels compared with control treated mice. ...
