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 New Gas phase Cascade Reactions of Stabilising Phosphorus Ylides Leading to Ring fused Indoles and Quinolines written by Lorna Murray and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthesis and flash vacuum pyrolysis (FVP) of stabilised phosphorus ylides containing an o-amino functionalised benzene ring has been examined for the first time. Model studies using N-methyl-N-tosyl and N-mesyl-N-methyl ylides showed that the ylides could be prepared, although yields were variable, and had the expected spectroscopic properties. Upon FVP, however, the expected loss of Ph3PO and the sulfonyl group was accompanied by unexpected transfer of the reactive site from nitrogen to carbon giving 3- substituted quinolines rather than the expected indole products. Moving to ylides with an [alpha]-cinnamoyl group (or heterocyclic analogue) did, however, result in the originally planned tandem cyclisation leading to ring-fused carbazole products. N-Benzyl was also found to be a suitable thermally labile group and a series of [alpha]-cinnamoyl N-benzyl-N-methyl ylides were prepared and characterised. For their synthesis, use of N-cinnamoylbenzotriazoles was found to be preferable to cinnamoyl chloride, requiring only half the amount of amino-functionalised phosphonium salt. While FVP of some of these ylides led to benzo-, furo- and thienocarbazoles in good yield, others again gave quinoline-type products pointing to a fine balance between the two alternative modes of cyclisation. It was noted that one of the furocarbazole products was very similar to a natural product, Eustifoline D, isolated from the medicinally active shrub Murraya euchrestifolia from Taiwan and its synthesis was planned. With a view to producing the required N-H carbazole, N, N-dibenzylamino amino ylides were prepared and were found to exhibit restricted rotation leading to broad NMR signals. Their FVP again led to both quinoline and carbazole products, with the former having usually, but not always, lost a phenyl group. Mechanistic pathways for the formation of the various products are proposed. Complete assignment of the complex 1H NMR spectra of the various fused-ring heterocyclic products was achieved, assisted by simulations in many cases. The ylide precursor required for Eustifoline D was prepared in five steps and 10% overall yield from 5-methylanthranilic acid. The final FVP step gave a quinoline as the major product, but the minor product was Eustifoline D, spectroscopically identical to the natural product.

Download or read book Organophosphorus Chemistry written by Ewies F. Ewies and published by LAP Lambert Academic Publishing. This book was released on 2015-04-20 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus ylides are steeped in the history of phosphorus chemistry (Bestmann et al., 1972, Cadogan, 1979, Emsley et al., 1976, Johnson, 1993, Kolodiazhnyi et al., 1983, Vedejs et al., 1986). Although they were known in 1894, (Michaelis et al., 1894) nevertheless the ylide chemistry did not flower until the Nobel-Prize Winning work of George Wittig and his students in 1953, (Wittig et al., 1953) resulting in the serendipitous discovery of the reaction bearing his name. An ylide can be defined as a substance in which the carbanion is attached directly to a heteroatom carrying a high degree of positive charge. The conventional Wittig reaction is an olefination process, entails the reaction of phosphonium ylide 1 with a carbonyl group. The resultant formation of an alkene 2 is undoubtedly one of the most valuable chemical reactions ever reported because of its simplicity, convenience and efficiency (Johnson, 1993, Kolodiazhnyi et al., 1983, Vedejs et al., 1986).
Download or read book Arrow Pushing in Inorganic Chemistry written by Abhik Ghosh and published by John Wiley & Sons. This book was released on 2014-07-25 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Involved as it is with 95% of the periodic table, inorganic chemistry is one of the foundational subjects of scientific study. Inorganic catalysts are used in crucial industrial processes and the field, to a significant extent, also forms the basis of nanotechnology. Unfortunately, the subject is not a popular one for undergraduates. This book aims to take a step to change this state of affairs by presenting a mechanistic, logical introduction to the subject. Organic teaching places heavy emphasis on reaction mechanisms - "arrow-pushing" - and the authors of this book have found that a mechanistic approach works just as well for elementary inorganic chemistry. As opposed to listening to formal lectures or learning the material by heart, by teaching students to recognize common inorganic species as electrophiles and nucleophiles, coupled with organic-style arrow-pushing, this book serves as a gentle and stimulating introduction to inorganic chemistry, providing students with the knowledge and opportunity to solve inorganic reaction mechanisms. • The first book to apply the arrow-pushing method to inorganic chemistry teaching • With the reaction mechanisms approach ("arrow-pushing"), students will no longer have to rely on memorization as a device for learning this subject, but will instead have a logical foundation for this area of study • Teaches students to recognize common inorganic species as electrophiles and nucleophiles, coupled with organic-style arrow-pushing • Provides a degree of integration with what students learn in organic chemistry, facilitating learning of this subject • Serves as an invaluable companion to any introductory inorganic chemistry textbook
