Primary anilines are essential building blocks to synthesize various pharmaceuticals, agrochemicals, pigments, electronic materials, and others. To date, the syntheses of primary anilines mostly rely on the reduction of nitroarenes or the transition-metal-catalyzed Ullmann, Buchwald-Hartwig and Chan-Lam cross-coupling reactions with ammonia, in which non-renewable petroleum-based chemicals are typically used as feedstocks via multiple step syntheses. A long-standing scientific challenge is to synthesize various primary anilines directly from renewable sources. Herein, we report a general method to directly convert a broad range of phenols into the corresponding primary anilines with the cheap and widely available hydrazine as both amine and hydride sources with simple Pd/C as the catalyst.

During our investigation to find suitable conditions to prepare very high molecular weight partially de-acetylated hyaluronic acid (HA), we discovered a powerful new method to cleave amide bonds using hydroxylamine salts at neutral pH with remarkable sele

RAF kinase plays a critical role in the RAF-MEK-ERK signaling pathway and inhibitors of RAF could be of use for the treatment of various cancer types. We have designed potent RAF-1 inhibitors bearing novel bicyclic heterocycles as key structural elements for the interaction with the hinge region. In both series exploration of the SAR was focussed on the substitution of the phenyl ring, which binds to the induced fit pocket. Overall, it was confirmed that incorporation of lipophilic substituents was needed for potent Raf inhibition and a number of potent analogues were obtained.
