Synthesis and SAR of 2-phenyl-1-sulfonylaminocyclopropane carboxylates as ADAMTS-5 (Aggrecanase-2) inhibitors
摘要:
A series of 1-sulfonylaminocyclopropanecarboxylates was synthesized as ADAMTS-5 (Aggrecanase-2) inhibitors. After an intensive investigation of the central cyclopropane core including its absolute stereochemistry and substituents, we found compound 22 with an Agg-2 IC(50) = 7.4 nM, the most potent ADAMTS-5 inhibitor reported so far.

catalyst‐free CH arylation methodology for the preparation of bi(hetero)aryls by the one‐pot reaction of anilines with tert‐butyl nitrite and (hetero)arenes under neutral conditions. The key step in this procedure is the in situ formation and subsequent photochemical (>300 nm) homolytic cleavage of a transient diazo anhydride intermediate. The generated aryl radical then efficiently reacts with a (hetero)arene

This invention relates to a method for for the production of a halogen-containing phthalocyaline compound by the cyclization of phthalonitrile compounds either singly or in combination with a metal compound, characterized in effecting the cyclization in an organic compound having a hydroxyl group and/or a carboxylic acid in an amount in the range of 0.01-10 mass parts per one mass part of the phthalonitrile compounds while continuing the introduction of an inert gas. This method, by using a solvent capable of serving as a specific oxygen source destined to participate in the reaction of complexing a metal compound introduced into a phthalocyanine dye, permits the production of a phthalocyanine compound inexpensively in a high yield.
imidazolium-containing mesoporous coordination polymer and organic polymer-based platforms were successfully exploited to develop single-site heterogenized Pd–NHC catalysts for oxidative arene/heteroarene C–H functionalization reactions. The catalysts were efficient in directed arene halogenation, and nondirected arene and heteroarene arylation reactions. High catalytic activity, excellent heterogeneity and
