Download or read book Application of sulfonium and sulfoxonium ylides in organocatalyzed asymmetric reaction written by Zhen-Hua Wang and published by OAE Publishing Inc.. This book was released on 2023-03-01 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sulfur-based ylides are very important and valuable reagents in organic synthesis and have been widely applied in the preparation of cyclic compounds and the formation of C-X (X = C, N, O, S, B, P) bond. Since the early 2000s, asymmetric organocatalysis has become a powerful strategy in organic synthesis (even highlighted by the 2021 Nobel Prize in Chemistry) and has attracted widespread research interest among synthetic organic chemists. In this area, a large number of outstanding achievements have been registered in the novel chiral catalysts design, new compounds synthesis, various reagents application, and versatile reaction discovery. Given the extensive application of sulfonium and sulfoxonium ylides in organic synthesis, in this review, we mainly summarize the organocatalyzed asymmetric reactions involving these ylide reagents as one of the reactants. Detailed reaction mechanisms, transition states and some synthetic applications are highlighted. The challenges and opportunities of this field are also discussed in the outlook.
Download or read book Phosphorus Ylides written by Oleg I. Kolodiazhnyi and published by John Wiley & Sons. This book was released on 2008-09-26 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Wittig first developed and described phosphorus ylides, nobody could have imagined how useful and versatile this class of compounds could be. This book provides a comprehensive and up-to-date compilation of the chemistry and applications of phosphorus ylides in organic synthesis. The ylides are discussed as reagents in the synthesis of a broad range of substances, amongst them olefins, acetylenes, cyclic and heterocyclic compounds, in such naturally occurring compounds as pheromones, steroids and carotenoids, and pharmaceutically and biologically active compounds such as antibiotics and prostaglandins. A particularly beneficial feature of this book is the 150 key experimental procedures with all the necessary data, allowing the preparation to start immediately without the need for an extremely time-consuming literature search. But should a search prove inevitable, around 2,500 references provide easy access to the primary literature. Every chemist in academia and industry working in organic, bioorganic, inorganic, and medicinal chemistry will welcome this book as an inspiration of concepts, ideas and practical syntheses.
Download or read book Modern Ylide Chemistry written by Viktoria H. Gessner and published by Springer. This book was released on 2018-05-08 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume covers recent advances in the chemistry of ylidic compounds with focus on their application in the design of ligands with unique donor properties, the development of novel organic transformations as well as the use of ylides in homogenous catalysis. Thereby, this volume particularly aims at the community of organic and organometallic chemists engaged in synthetic chemistry and catalysis as well as in the use of special ligands for the stabilization of unusual main group element species and the “transition-metal free” activation of element-element/hydrogen bonds. These fields of research are highly active and vivid research areas to which ylide chemistry has only recently started to contribute, but has already led to fascinating developments in most different directions. This volume highlights these recent developments, thus giving not only an overview over the past achievements, but also possibilities for future applications. To this end, the chapters selected in this volume combine different aspects of ylide chemistry, starting with theoretical aspects in ligand design followed by synthetic organic methods, catalytic transformations and complex chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides researchers in the fields of organic chemistry, organometallic chemistry and homogeneous catalysis with an overview of recent developments in the applications of reactions involving carbene and nitrene intermediates directed to the synthesis of heterocyclic compounds. Multiple pathways through which diverse heterocyclic compounds are accessed occur from a variety of carbene and nitrene precursors through C-H/X-H insertions, cycloadditions, ylide transformations, rearrangements, and cascade reactions. Catalytic processes that form metallo-carbenes and nitrenes offer unparalleled chemo-, regio-, and stereo-selectivities. Insights are provided into the scope of these methodologies and the inherent control of catalyst ligands on reaction selectivities.

Available in PDF, EPUB and Kindle. Book excerpt: Organic chemistry is a core part of the chemistry curricula, andadvanced levels texts often obscure the essential frameworkunderlying and uniting the vast numbers of reactions as a result ofthe high level of detail presented. The material in this book iscondensed into a manageable text of 350 pages and presented in aclear and logical fashion, focusing purely on the basics of thesubject without going through exhaustive detail or repetitiveexamples.
