Pages : 539
Book Description
Authored by one of the leading experts in the field, this is the only comprehensive overview of chiral organophosphorus compounds, from asymmetric synthesis to catalysis and pharmacological applications. As such, this unique reference covers the chemical background as well as spectroscopical analysis of phosphorus compounds, and thoroughly describes all the various synthetic strategies for these substances. Metal-, organo- and biocatalyzed reactions for the introduction of phosphorus are explained as are asymmetric oxidation and reduction methods for the preparation of all possible oxidation states of phosphorus. The text also includes industrial applications for these compounds. Of particular interest to chemists working in the field of asymmetric synthesis, as well as to the pharmaceutical industry due to the increasing number of phosphorous-containing drugs.

Asymmetric Synthesis of Organophosphates and Their Derivatives

Pages : 106
Book Description
Organophosphorus compounds (OPs) are widely used in the agricultural industry especially in the pesticide market. Phosphates play a huge role as biological compounds in the form of energy carrier compounds like ATP, and medicine as antivirals. OPs have become increasingly important as evidenced by the publication of new methods devoted to their uses and synthesis. These well-established studies lay the basis for industrial organic derivatives of phosphorus preparations. The current work explored methods of synthesizing chiral organophosphate triesters. We experimented with different processes roughly divided into either an electrophilic or nucleophilic strategy using chiral Lewis acids, organocatalysts (HyperBTM), activating agents, and chiral auxiliaries with the goal of control stereoselectivity. These methods were explored through the use of different starting materials like POCl3, triethyl phosphate, methyl phosphordichloradate, and PSCl3. My research results suggest that most of the reactions only went to partial completion. Furthermore, most of the experiments were either non-effective product or the scientific data were not productive in the reaction, in fact, the product could not be isolated or purified. The synthesis reaction steps were evaluated through TLC, 1H NMR, and 31P NMR.

ISBN: 9780198502623
Category : Science
Languages : en
Pages : 296
Book Description
Organophosphorus Chemistry: A Practical Approach in Chemistry provides a practical introduction to the field by mixing a brief review of the subject area with key experimental details and sample procedures. Phosphorus is an element that has been central to the development of our modern way of life. Its chemistry plays a key role in the development of such important areas as pharmaceuticals, agrochemicals, modern materials and molecular biology. Much of this work requires a sound understanding of the organic chemistry of phosphorus and this volume is designed to instruct the reader in the essential methodology used. Topics covered include phosphines, applications of phosphorus (III) and (V) compounds as reagents in synthesis, the chemistry of phosphorus ylides, applications of the Wittig reaction in the synthesis of heterocyclic and carbocyclic compounds, preparation of Iminophosphoranes and their synthetic applications in the aza-Wittig reaction, phospho-transfer processes leading to [P-C] bond formation, low valent phosphorus compounds and phosphorus methods in oligonucleotide chemistry. It is intended not only for the specialist in organophosphorus chemistry, but also for the organic chemist with little experience in the field who wishes to add phophorus-based techniques to his or her ensemble of synthetic methods.
