  • Publisher: Springer

This brief presents a valuable and concise overview of organocatalytic methodologies in carbohydrate chemistry. It includes glycosylation processes with de novo syntheses of carbohydrates and chain elongation of carbohydrates. The author, an academic of international distinction, goes on to make comparisons between traditional organic and metalorganic transformations.

Modern Aldol Reactions, 2 Volume Set

At long last, the complete spectrum of the aldol reaction is presented here in this two-volume handbook. Top authors guarantee contributions of the highest quality, beginning with fundamentals and then moving on to enolates and catalytic aldol reactions, including the Mukaiyama Reaction. Further sections are devoted to enzymatic aldol reactions in synthesis as well as such related reactions as the Henry, Ene and Aldol-Tishchenko reactions. The wealth of information contained here allows a comprehensive overview of this important topic in organic chemistry, removing the need for the hitherto time-consuming research among the widely dispersed literature. With a foreword by Professor D. A. Evans.

Enantioselective Organocatalyzed Reactions I

Organocatalyzed Reactions I and II presents a timely summary of organocatalysed reactions including: a) Enantioselective C-C bond formation processes e.g. Michael-addition, Mannich-reaction, Hydrocyanation (Strecker-reaction), aldol reaction, allylation, cycloadditions, aza-Diels-Alder reactions, benzoin condensation, Stetter reaction, conjugative Umpolung, asymmetric Friedel-Crafts reactions; b) Asymmetric enantioselective reduction processes e.g. Reductive amination of aldehydes or ketones, asymmetric transfer hydrogenation; c) Asymmetric enantioselective oxidation processes; d) Asymmetric epoxidation, Bayer-Villiger oxidation; e) Enantioselective a-functionalization; f) A-alkylation of ketones, a-halogenation and a-oxidation of carbonyl compounds.

Aldol Reactions

Aldol Reactions provides a comprehensive up-to-date overview of aldol reactions including application of different metal enolates; catalytic aldol additions catalyzed by different Lewis acids and Lewis bases; enantioselective direct aldol additions; antibodies and enzyme catalyzed aldol additions and the recent aggressive development of organocatalyzed aldol additions. The power of each method is demonstrated by several applications in total synthesis of natural products. The pros and cons of these methodologies with regard to stereoselectivity, regioselectivity and application in total synthesis of natural products are discussed. Great importance is set to the diverse possibilities of the manual of aldol reaction to install required configurations in complicated natural product synthesis.

Modern Methods in Stereoselective Aldol Reactions

The selective formation of bondings between molecules is one of the major challenges in organic chemistry, and the so-called aldol reaction is one of the most important for this purpose. These reactions are a highly useful tool for developing such novel substances as natural products and pharmaceuticals. Likes its highly successful and much appreciated predecessor, "Modern Aldol Reactions", this ready reference provides a systematic overview of methodologies for installing a required configuration during an aldol addition step, but shifts the focus so as to cover the latest developments. As such, it presents a set of brand new tools, including vinylogous Mukaiyama-aldol reactions and substrate-controlled aldol reactions, as well as asymmetric induction in aldol additions. Furthermore, new developments in existing stereoselective aldol additions are described, such as the deployment of supersilyl groups or organocatalyzed aldol additions. All of these methodologies are presented in the context of their deployment in the total synthesis of natural products.

Domino and Intramolecular Rearrangement Reactions as Advanced Synthetic Methods in Glycoscience

The book consists of a brief introduction, a foreward provided by professor Danishefsky of Columbia University, and about 14 - 16 chapters, each written by one or two eminent scholars/authors describing their recent research in the area of either domino reactions or intramolecular rearrangements in carbohydrate chemistry. Three or four chapters will be reviews. The domino (cascade, tandem) reactions are always intramolecular. They are usually very fast, clean and offer highly complex structures in a one pot process. Intramolecular rearrangements offer very similar advantages and often lead to highly complex products as well. Although many recently isolated carbohydrates fulfill various sophi...
