Indium-Catalyzed Regioselective β-Alkylation of Pyrroles with Carbonyl Compounds and Hydrosilanes and Its Application to Construction of a Quaternary Carbon Center with a β-Pyrrolyl Group
studies showed the following three aspects: (1) dipyrrolylalkanes produced in situ from the pyrrole and carbonylcompound are key intermediates, (2) the selective β-alkylation is attributed to the selective elimination of an α-pyrrolyl group from the dipyrrolylalkane intermediates, and (3) the indium Lewis acidcatalyst is indispensable for the progress of both stages.

The present invention relates to apoptosis signal-regulating kinase 1 ("ASK1") inhibiting compounds of the formula (I) wherein the variables are as defined herein. The invention also relates to pharmaceutical compositions, kits and articles of manufacture comprising such compounds; methods and intermediates useful for making the compounds; and methods of using said compounds.
Photodynamictherapy (PDT) is a promising alternative to cancertherapy for its non-invasive advantage. The rationaldesign of ideal photosensitizers (PSs) is especially significant in PDT. Herein, we synthesized a diiodo-substituted BODIPY (SNBDP) with near-infrared (NIR) region absorption and fluorescence emission by Knoevenagel condensation reaction. The SNBDP nanoparticles (NPs) were prepared by
