called the melatoninrhythmenzyme, is thought to play an important regulatory role in circadian rhythm in animals and people. A series of analogues were synthesized in which indole and coenzyme A were linked via ketone tethers as designed inhibitors of this enzyme. These compounds were tested against purified serotonin N-acetyltransferase. The parent ketone compound was found to be as potent as an amide

drugs. Here, we describe a new method for the synthesis of triazenes. The procedure involves a reagent which is rarely used in synthetic organic chemistry: nitrousoxide (N2O, “laughing gas”). Nitrousoxide mediates the coupling of lithium amides and organomagnesium compounds while serving as a nitrogen donor. Despite the very inert character of nitrousoxide, the reactions can be performed in solution
The reactions of bis (trimethylsilyl) peroxide with alkyl, vinyl, alkynyl, aromatic and heteroaromatic anions are described. Depending on the reaction conditions, the trimethylsilyloxy derivatives can be obtained alone or together with the corresponding trimethylsilyl derivatives, which is sometimes the major product. Enolates, generated using magnesium diisopropylamide give the corresponding hydroxycarbonyl

unprecedented substitution of a nitro group with aryl or alkenyl groups of Grignard reagents affords 2-aryl or alkenylpyridine N-oxides in modest to high yields with high chemoselectivity. This protocol allows a simple and clean synthesis of various 2-substituted pyridineN-oxides and the corresponding pyridine derivatives. Furthermore, straightforward one-pot iterative functionality of pyridineN-oxides could

The present invention relates to a novel method for preparing triazenes. Further, the invention relates to novel triazenes and the use of N2O for preparing a compound comprising a triazene group. Further, the invention relates to the use of the novel triazenes as a medicament, in particular in the treatment of cancer.
