A new palladium-catalyzed C(sp3)–H amination reaction has been developed. 1-(tert-Butyl)-2-iodobenzene and its derivatives undergo palladium-catalyzed C–H activation to form palladacycles. The palladacycles are aminated with diaziridinone to form indolines as the final products. The reaction represents a new method for the synthesis of 3,3-disubstituted indolines, which are essential structural motifs
directing goups represents an attractive strategy for C−H functionalization. A two C−H alkylation system, initiated by the oxidative addition of organohalides to Pd0, has been developed. The first reaction involves an intermolecular alkylation of palladacycles to form C(sp3)−C(sp2) bonds followed by C(sp2)−H activation/cyclization to deliver alkylated benzocyclobutenes as the final products. In the second
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.
