The synthesis of aromatic amines is of utmost importance in a wide range of chemical contexts. We report a direct amination of boronic acids with nitro compounds to yield (hetero)aryl amines. The novel combination of a dioxomolybdenum(VI) catalyst and triphenylphosphine as inexpensive reductant has revealed to be decisive to achieve this new C−N coupling. Our methodology has proven to be scalable,

The invention relates to compounds of Formula (0): wherein A1-A8, R4 and R5 each has the meaning as described herein. Compounds of Formula (0) and pharmaceutical compositions thereof are useful in the treatment of diseases and disorders in which undesired or over-activation of NF-kB signaling is observed.
Herein, we developed a copper‐mediated Chan‐Lam type O‐arylation of arylhydroxylamines with arylboronic acids to generate transient N,O‐diarylhydroxylamines that could rapidly undergo cascade [3,3]‐sigmatropic rearrangement and rearomatization to afford NOBIN (2‐amino‐2′‐hydroxy‐1,1′‐binaphthyl) analogues under mild conditions. The newly synthesized racemic biaryl products can be further resolved by
