AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
C-C and C-N bonds are some of the most common structures in molecules ranging from drugs to catalysts and to food additives. Many coupling reactions were developed to form these types of bonds with excellent selectivity and good performance. Still, the syn ...
We report herein the enantioselective total synthesis of three monoterpene indole alkaloids, namely, (+)-alstilobanine C, (+)-undulifoline, and (-)-alpneumine H. The key features of our synthesis include: a) introduction of chirality via enantioselective d ...
Organic chemistry is essential for the development of a modern society and technical progress requires the continuous development of synthetic methodologies Novel, efficient, selective and flexible protocols are employed to access complex frameworks from s ...
An efficient CpxRhIII‐catalyzed enantioselective alkenyl C−H functionalization/[4+1] annulation of acryl amides and allenes is reported. The described transformation provides straightforward access to enantioenriched α,β‐unsaturated‐γ‐lactams bearing a qua ...
The work presented in this thesis focuses on the synthesis of monoterpene indole alkaloids.
The first part describes the development of a general methodology to provide an enantioenriched platform, useful for the convergent synthesis of Akuammiline alkalo ...
Among the fundamental chemical transformations in organic synthesis, rearrangement has been recognized as powerful and reliable reactions for the construction of carbon-carbon or carbon-heteroatom bonds. Benefiting from the advance of the novel catalytic s ...
We report herein the first examples of catalytic enantioselective synthesis of axially chiral 3-arylpyrroles. Reaction of a-isocyanoacetates with b-aryl-a,b-alkynic ketones in the presence of silver oxide and a phosphine ligand derived from Cinchona alkalo ...
The total synthesis of pentacyclic monoterpene indole alkaloids is the focus of this thesis.
Total syntheses of (±)-alstilobanine C, (±)-undulifoline and (±)-alstilobanine B, three natural products from the Ulean family of alkaloids, were accomplished. The ...
An enantioselective total synthesis of (-)-terengganensine A, a heptacyclic monoterpene indole alkaloid, was performed. A short sequence allowed to obtain the enantio-enriched target in good overall yield. The synthesis featured a key asymmetric transfer h ...
We report herein a strategy to construct enantiopure inherently chiral macrocycles, ABCD-type heteracalix[4]-aromatics, through a catalytic enantioselective intramolecular C−N bond forming reaction. A chiral ligand-palladium complex was found to efficientl ...
