To date, more than 100 congeners of the akuammiline alkaloid family have been isolated. Their signature structural element is a methanoquinolizidine moiety, a cage-like scaffold structurally related to adamantane. The structural variations of the family members originate from oxidative processes that mostly trigger rearrangements of the methanoquinolizidine motif. The family of the akuammiline alkaloids is best represented by strictamine. It bears the least functionalized carbon skeleton of all family members without lacking the signature structural motifs. Herein, we report the formal synthesis of strictamine through a Stevens [2,3]-sigmatropic rearrangement as a key step and the synthetic pitfalls related with its synthesis.

Histone lysine demethylases (KDMs) are of critical importance in the epigenetic regulation of gene expression, yet there are few selective, cell-permeable inhibitors or suitable tool compounds for these enzymes. We describe the discovery of a new class of inhibitor that is highly potent towards the histone lysine demethylases KDM2A/7A. A modular synthetic approach was used to explore the chemical space and accelerate the investigation of key structure–activity relationships, leading to the development of a small molecule with around 75-fold selectivity towards KDM2A/7A versus other KDMs, as well as cellular activity at low micromolar concentrations.

For decades, akuammiline alkaloids have attracted synthetic chemists due to their intriguing molecular architecture. Among the different structural elements embedded in their carboskeleton, the methanoquinolizidine system constitutes the signature structu

A practical and efficient synthesis of various 1,2,5-tricarbonyl compounds is described. The synthesis has been carried out by a conjugate addition of methyl cyanoacetate to the β-position of α,β-unsaturated carbonyl compounds and a subsequent copper(I) iodide-catalyzed aerobic oxidation. In addition, various α-aryl- and α-alkyl-α-keto esters have been synthesized using a similar approach. Copyright

experimental part, p. 3332 - 3338 (2010/11/20)
Various approaches to [2-fluoro-4-(trifluoromethyl)phenyl]acetonitrile were investigated. Two of these methods were selected and applied to a variety of electron-deficient substrates, thereby expanding the scopes of the procedures.

The mechanistic pathway proposed by Zhang et al. (Zhang, X.-M.; Yang, D.-L.; Liu, Y.-C.J.Org.Chem. 1993, 58, 224) for nucleophilic substitution of halogen in o- and p-halonitrobenzenes, SET and nonchain radical process, was shown to be based on erronous e
Effects of Electron Acceptors and Radical Scavengers on Nonchain Radical Nucleophilic Substitution Reactions

The yields of reaction products from thermal nucleophilic substitution reactions in dimethyl sulfoxide (DMSO) of six o- and p-nitrohalobenzenes (1) with sodium salt of ethyl α-cyanoacetate carbanion (2) were found to be markedly diminished by addition of small amounts of strong electron acceptors (p-dinitrobenzene, m-dinitrobenzene, and o-dinitrobenzene) (Table II), but little or no diminished effects on the yields of reaction products were observed by addition of radical scavengers ( such as galvinoxyl, nitroxyl, etc.) (Table III).The results are consistent with the conclusion that these reactions proceed via a nonchain radical nucleophilic substitution mechanism.
