Palladium-Catalyzed Highly Selective ortho-Halogenation (I, Br, Cl) of Arylnitriles via sp2 C–H Bond Activation Using Cyano as Directing Group
摘要:
A palladium-catalyzed ortho-halogenation (I, Br, Cl) of arylnitrile is described. The optimal reaction conditions were identified after examining various factors such as catalyst, additive, solvent, and reaction temperature. Using cyano as the directing group, the halogenation reaction gave good to excellent yields. The method is compatible to the arylnitriles with either electron-withdrawing or electron-donating groups. The reaction is available to the substrate in at least gram scale. The present method was successfully applied to the synthesis of the precursors of paucifloral F and isopaucifloral F.

represents one of the first examples of the addition of an organopalladium moiety to the carbon-nitrogentriplebond of a nitrile. The reaction is compatible with a number of functional groups. A reaction mechanism, as well as a model accounting for the electronic effects of substituents on the aromatic ring of the nitrile, is proposed.
The present invention relates to HSP90 inhibitors containing fused amino pyridine core that are useful as inhibitors of HSP90 and their use in the treatment of HSP90 related diseases and disorders such as cancer, an autoimmune disease, or a neurodegenerative disease.

The invention relates to novel compounds of formula I which are inhibitors of deubiquitylating enzymes (DUBs) and/or desumoylating enzymes. In particular, the invention relates to the inhibition of ubiquitin C-terminal hydrolase 7 or ubiquitin specific peptidase 7 (USP7). The invention further relates to methods for the preparation of these compounds and to their use in the treatment of cancer.

Synthesis of isocoumarins and related compounds via triflic acid promoted hydrolysis/cyclization sequence of 2-(alkynyl)benzamides under microwave condition was achieved. The substrate scope of the reaction was broad to include not only aromatic but also polyaromatic and heteroaromatic motifs, thus highlighting the significance of this methodology. One-pot operation, short reaction time, good chemical
