Download or read book Synthesis and Reactivity of Donor-Acceptor Substituted Aminocyclopropanes and Aminocyclobutanes written by Florian de Nanteuil and published by Springer. This book was released on 2015-09-26 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a general approach to accessing nitrogen-substituted hetero- and carbocycles. In short, the annulation reactions developed in the thesis make it possible to access nitrogen-substituted four-, five- and six-membered rings, all essential building blocks for the synthesis of bioactive molecules. Many natural products display a saturated polycyclic core allowing a well-defined arrangement of functional groups in space. As such, they can interact with biological targets with a high degree of affinity and selectivity, surpassing many synthetic drugs. Nevertheless, the efficient synthesis of such complex ring systems poses a challenge for organic chemistry. Through careful tuning of the electronic properties of a nitrogen donor group and a diester acceptor group, the first [3+2] annulation reaction between aminocyclopropanes and enol ethers or carbonyl compounds is now possible. The reaction proceeded under mild catalytic conditions, and the building blocks obtained can be found at the core of bioactive alkaloids, drugs such as Ramipril and biomolecules such as DNA and RNA. Thanks to the dynamic kinetic asymmetric annulation of aminocyclopropanes with enol ethers and aldehydes, access to enantioenriched compounds is also now possible. Lastly, a synthesis of donor-acceptor aminocyclobutanes via [2+2] cycloaddition using a cheap iron catalyst was developed, allowing them to be used in [4+2] annulations to access cyclohexylamines.

Book Synopsis Catalytic Reduction in Organic Synthesis by : Johannes G. de Vries
Download or read book Catalytic Reduction in Organic Synthesis written by Johannes G. de Vries and published by Thieme Chemistry. This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Catalytic reductions are among the most used synthetic transformations, and the past 15 years have seen great progress in this field. Science of Synthesis: Catalytic Reduction in Organic Synthesis includes the latest developments, as well as selective coverage of more well-established methods. Both heterogeneous and homogeneous catalytic systems are covered, and enantioselective methodology is well represented. There is a focus on the use of metal nanoparticles, both in suspension as well as on solid supports. Furthermore, the advent of research on the conversion of renewable resources into fuels and chemicals has given a great impetus to the field, as deoxygenations are often the first step in the conversion of biomass and this can often be achieved using hydrogenation or hydrogenolysis reactions. Scope, limitations, and mechanism of the reactions are discussed and key experimental procedures are included.
