Carboxylic Ortho Acid Derivatives Preparation And Synthetic Applications

eBook Download

BOOK EXCERPT:

Carboxylic Ortho Acid Derivatives: Preparation and Synthetic Applications discusses the principal classes of ortho acid derivatives and their preparation, properties, and reactions. The book is a critical survey and attempts to collate literature regarding the wide array of information on ortho acid derivatives to be of use to chemists studying different sorts of problems. The text is divided into seven chapters, where Chapter 1 begins with a discussion of the general concepts of carboxylic ortho esters, their synthesis, and properties. Chapters 2 to 4 tackle reactions of ortho esters that result to different bonds and bond formations such as (a) carbon-oxygen and carbon-halogen bond, (b) carbon-nitrogen or carbon-phosphorus, and (c) carbon-carbon or carbon-hydrogen bond formation. Chapter 5 discusses the synthesis, properties, and applications of carbohydrate ortho esters. Related compounds and their properties, preparation, and chemical transformations are the topic of Chapters 6 and 7. Some of these compounds are trithioorthocarboxylates, tetrathioorthocarbonates, and amide acetals. The book is a valuable reference to students or anyone else interested in chemistry.

Catalysis In Micellar And Macromoleular Systems

eBook Download

BOOK EXCERPT:

Catalysis in Micellar and Macromolecular Systems provides a comprehensive monograph on the catalyses elicited by aqueous and nonaqueous micelles, synthetic and naturally occurring polymers, and phase-transfer catalysts. It delineates the principles involved in designing appropriate catalytic systems throughout. Additionally, an attempt has been made to tabulate the available data exhaustively. The book discusses the preparation and purification of surfactants; the physical and chemical properties of surfactants and micelles; solubilization in aqueous micellar systems; and the principles of micellar catalysis. Separate chapters cover micellar catalysis of hydrolyses, solvolyses, aminolyses, and miscellaneous ionic reactions; micellar effects on organic equilibria and nucleophilic substitution reactions, and on hydrophobic interactions and protein structure; and radical and excited state reactions in micellar systems. The final chapters deal with interactions in and catalysis by micelles in nonaqueous solvents and in liquid crystalline phases; and catalysis in macromolecular and related systems. This book is aimed at the industrial and academic researcher regardless of his arbitrarily defined subfield, be it organic, inorganic, biological, colloid, etc. The treatment provides guidance and stimulus to bioorganic, inorganic, pharmaceutical, colloid, physical, and polymer chemists as well as to those who seek novel and unique catalysts in industrial processes. It can also serve as the basis of a graduate course.

Amino Acids Insights And Roles In Heterocyclic Chemistry

eBook Download

BOOK EXCERPT:

This first-of-its-kind four-volume book series, Amino Acids: Insights and Roles in Heterocyclic Chemistry, provides readers with up-to-date information on alpha-amino acids, the potential challenges in working with alpha-amino acids, the protecting groups for the carboxyl, amino and side chain groups of the amino acids, and the most popular heterocyclic compounds that are originating from alpha-amino acids. These heterocyclic compounds include hydantoins, thiohydantoins (including 2-thiohydantoins, 4-thiohydantoins, 2,4-dithiohydantoins), 2,5-diketopiperazines, N-carboxyanhydrides, N-thiocarboxyanhydrides, sydnones, sydnonimines, azlactones, pseudoazlactones, and oxazolidin-5-ones. This is the first resource to comprehensively collect all the heterocycles that can be directly prepared from alpha-amino acids. In addition, almost all kinds of synthetic methods for a particular type of heterocycles from alpha-amino acids are included, along with the detailed mechanistic discussions and experimental procedures. Volume 1: Protecting Groups collects and discusses the 260 protecting groups relating to amino acids, which have been organized by carboxyl group, amino group, and side chain groups. The conditions to introduce these protecting groups as well as their deprotecting procedures have also been incorporated, along with the physical properties, solvent effects, and temperature effects on the solubility of amino acids. It presents the solubility of glycine and phenylalanine in a variety of solvent systems to show the impact on amino acid, where glycine generally represents the polar amino acid whereas phenylalanine represents the amino acid of non-polar side chain. In Volume 2: Hydantoins, Thiohydantoins, and 2,5-Diketopiperazines, the author has compiled the three IUPAC accepted nomenclature systems for heterocyclic compounds, which will be very useful for readers working in the heterocyclic chemistry field for giving the synthesized molecules their correct names. In addition, three groups of heterocyclic compounds, i.e., hydantoins, thiohydantoins (including 2-thiohydantoin, 4-thiohydantoin and 2,4-dithiohydantoin), and 2,5-diketopiperazines, have been organized with updated literature information. Particularly, all three groups of heterocyclic compounds have demonstrated many important biological activities, particularly anticancer and antibacterial activities. On the other hand, these three groups of heterocycles can be applied as substrates to make other chemical derivatives, particularly novel unnatural amino acids. All their reactivities have been compiled and updated. These will be very valuable for readers who have been working in this area or have interest in this area. Volume 3: N-Carboxyanhydrides, N-Thiocarboxyanhydrides, and Sydnones presents up-to-date detailed information on two types of heterocyclic compounds that are originated from alpha-amino acids: NCAs/NTAs and sydnones/sydnonimines. The volume also covers the more than 10 initiating systems for the NCA monomers to undergo the ring-opening polymerization, which are very useful for readers in order to make living polypeptides/polypeptoids. In addition, the method to characterize these prepared polypeptides/polypeptoids are included. Particularly, two modern mass spectrometric techniques (MALDI-TOF and ESI-TOF) have been explained with detailed examples, where the elucidation of molecular weight of protein based on the ESI-TOF spectra have been given with a practical example as well as the theory that is based on, a unique feature of the volume. Volume 4: Azlactones and Oxazolidin-5-ones discusses two types of simple heterocycles that can be prepared from alpha-amino acids, i.e., azlactones (also known as oxazolones, 4-unsaturated azlactones included) and oxazolidin-5-ones. These heterocyclic compounds behave differently in both biological and chemical properties, and their biological activities are presented in a well-organized manner in this volume. This unique 4-volume set thoroughly covers more than seven types of heterocyclic compounds that are originated from alpha-amino acids, providing carefully compiled updated information with detailed examples. The author has shared many thoughtful insights based on his strong background in physical organic chemistry. The volumes will be highly valuable for graduate students and senior students, as well as for professors and researchers working in the field of medicinal and pharmaceutical chemistry, organic chemistry, organic synthesis, heterocycles, and proteins and peptides.
