Download Chiral Building Blocks in Asymmetric Synthesis Book in PDF, ePub and Kindle
Chiral Building Blocks in Asymmetric Synthesis A comprehensive introduction to the important classes of chiral building blocks Chirality — the asymmetric quality found in certain chemical compounds — plays an essential role in our world: chiral compounds can be found in biology, pharmaceutical compounds, agrochemicals, and fragrances. The stereoselective preparation of these complex molecular constructions constitutes a challenge. To this end, modern asymmetric synthesis utilizes a variety of valuable and efficient reagents employed as chiral auxiliaries, metal complexes and organocatalysts in stereoselective catalysis, and enantiopure reactants termed as chiral building blocks. In Chiral Building Blocks in Asymmetric Synthesis, the achievements in the fields of preparation of and applications of chiral blocks are presented. In doing so, the book comprehensively discusses the important classes of these reactants as the key for the asymmetric synthesis of chiral molecules. As such, it is an indispensable resource about synthetic methods, as well as possible modifications and transformations of important classes of chiral compounds. It also highlights the importance of their use as reactants and auxiliaries in the preparation of more sophisticated molecules or supramolecular systems. In Chiral Building Blocks in Asymmetric Synthesis readers will also find: Organization according to the most important compound classes — e.g. amino acids, BINOL and its derivatives, terpenes, and others — with an emphasis on synthesis and application A focus on the use of chiral building blocks for the preparation of bioactive compounds and supramolecular assemblies Chiral Building Blocks in Asymmetric Synthesis is a useful reference for organic chemists, catalytic chemists, chemists in industry, medicinal chemists, pharmaceutical chemists, and the libraries that support them.

Download Asymmetric Synthesis of Three-Membered Rings Book in PDF, ePub and Kindle
The first handbook to focus on the asymmetric synthesis of different types of three-membered rings. The outstanding and experienced authors have an excellent international reputation and cover cyclopropanes, epoxides and aziridines as well as chiral oxaziridines in equal measure. To this end, they describe in detail different synthetic approaches starting with chiral substrates as well as the application of chiral metal- or organocatalysts. Furthermore, methods for the kinetic resolution of initially racemic products are treated alongside recent advances and novel developments in established techniques for the synthesis of three-membered rings. With its structured composition this is of high interest to scientists in methodological and natural product synthesis as well as those in industrial and pharmaceutical chemistry.

Download Chiral Reagents for Asymmetric Synthesis Book in PDF, ePub and Kindle
Derived from the renowned, Encyclopedia of Reagents for Organic Synthesis (EROS), the related editors have created a new handbook which focuses on chiral reagents used in asymmetric synthesis and is designed for the chemist at the bench. This new handbook follows the same format as the Encyclopedia, including an introduction and an alphabetical arrangement of the reagents. As chiral reagents are the key for the successful asymmetric synthesis, choosing the right reagents is essential, in this handy reference the editors give details on how to prepare, store and use the reagents as well as providing key reactions to demonstrate where reagents have been successfully used. Comprehensive information on 226 reagents Covers 64 reagents which were not included in EROS All information in one easy to use volume – at an affordable price All reagents included will be added to e-EROS – please visit the site where you can gain access to over 50,000 reactions and 3,800 of the most frequently consulted reagents.

Download Design, Synthesis and Evaluation of Chiral Auxiliaries, Ligands and Catalysts for Asymmetric Synthesis Book in PDF, ePub and Kindle
Task definition theoretically is one of the main components of self-regulated learning because one's representation of the task directs cognitive activities such as setting goals, creating plans, and enacting those plans to create task products. To date, little research has examined students' representations of tasks or how those representations change over time. In this dissertation I characterize students' initial representations of tasks and explore factors influencing how they refine these representations over time. Fifty-eight undergraduate students taking an undergraduate instructional psychology course participated in a semester-long examination of how students constructed and refined their task understanding. The data source was a studying portfolio consisting of detailed descriptions about and reflections on strategic processes they used to complete two main writing assignments in the course: a think paper and a design project. Analyses of these data suggest students' representations of tasks varied across two dimensions: breadth and depth. In terms of breadth, students selected information from the design project description of different grain sizes. Students with greater depth not only searched and selected information from the task, but they actively assembled elements of the task and monitored how those components fit with one another. Most students set goals and created plans; however, not all goals or plans were framed in light of criteria that would theoretically foster self-regulated learning. To revise task understanding, students metacognitively monitored their processes and outcomes of learning activities, which updated information about task, cognitive, and motivational conditions. This additional information afforded students opportunity to reassess the discrepancy between the initial state and the goal state to determine next steps to reach task goals. Although students may have recognized the need to change their approaches, they often failed to engage in effective metacognitive control to adapt approaches to learning. I interpret this to indicate that control processes require not only the skill for enacting these processes but also the motivational catalyst to sustain these efforts when competing factors are present. Future research should strive to create new measures for task understanding, and to track how students' perceptions and representations of tasks influence self-regulated learning and achievement.

The goal of this book is to show the high potential of chiral sulfur-containing ligands to promote numerous asymmetric catalytic transformations. These ligands can now be recognised as real competitors to the more usual phosphorus- or nitrogen-containing ligands.

Download Privileged Chiral Ligands and Catalysts Book in PDF, ePub and Kindle
Catalytic asymmetric synthesis has been one of the most active research areas in chemistry (Nobel Prize in 2001). The development of efficient chiral catalysts plays a crucial role in asymmetric catalysis. Although many chiral ligands/catalysts have been developed in the past decades, the most efficient catalysts are derived from a few core structures, called "privileged chiral catalysts". This ultimate "must have" and long awaited reference for every chemist working in the field of asymmetric catalysis starts with the core structure of the catalysts, explaining why a certain ligand or catalyst is so successful. It describes in detail the history, the basic structural characteristics, and the applications of these "privileged catalysts". This novel presentation provides readers with a much deeper insight into the topic and makes it a must-have for organic chemists, catalytic chemists, chemists working with/on organometallics, chemists in industry, and libraries.
