Book Description
Strategies and Tactics in Organic Synthesis, Volume 3 provides detailed accounts of interesting advances in the field of synthesis. This book discusses the tasks of multistep synthesis from finding the proper reagents, reaction, and conditions for individual steps to inventing new chemistry to fill gaps in existing synthetic methodology. Organized into 13 chapters, this volume begins with an overview of the development of redox glycosidation strategy through ester methylenation. This text then examines the development of computer-assisted molecular modeling with applications to a wide range of problems in biological and organic chemistry. Other chapters consider the medicinal significance of ginkgo tree, which has prompted systematic studies to correlate the claimed beneficial effects of its extracts to the active principles. This book discusses as well the biological potency of pentacyclic quassinoids. The final chapter deals with the economic synthesis of a penem antibacterial. This book is a valuable resource for chemists.

Book Description
A classic in the area of organic synthesis, Strategies and Tactics in Organic Synthesis provides a forum for investigators to discuss their approach to the science and art of organic synthesis. Rather than a simple presentation of data or a second-hand analysis, we are given stories that vividly demonstrate the power of the human endeavour known as organic synthesis and the creativity and tenacity of its practitioners. First hand accounts of each project tell of the excitement of conception, the frustration of failure and the joy experienced when either rational thought and/or good fortune give rise to successful completion of a project. In this book we learn how synthesis is really done and are educated, challenged and inspired by these stories, which portray the idea that triumphs do not come without challenges. We also learn that we can meet challenges to further advance the science and art of organic synthesis, driving it forward to meet the demands of society, in discovering new reactions, creating new designs and building molecules with atom and step economies that provide solutions through function to create a better world.- Personal accounts of research in organic chemistry. - Written by internationally renowned scientists.- Details state of the art organic synthesis.

Book Description
Bridging the Gap Between Organic Chemistry Fundamentals and Advanced Synthesis Problems Introduction to Strategies of Organic Synthesis bridges the knowledge gap between sophomore-level organic chemistry and senior-level or graduate-level synthesis to help students more easily adjust to a synthetic chemistry mindset. Beginning with a thorough review of reagents, functional groups, and their reactions, this book prepares students to progress into advanced synthetic strategies. Major reactions are presented from a mechanistic perspective and then again from a synthetic chemist’s point of view to help students shift their thought patterns and teach them how to imagine the series of reactions needed to reach a desired target molecule. Success in organic synthesis requires not only familiarity with common reagents and functional group interconversions, but also a deep understanding of functional group behavior and reactivity. This book provides clear explanations of such reactivities and explicitly teaches students how to make logical disconnections of a target molecule. This new Second Edition of Introduction to Strategies for Organic Synthesis: Reviews fundamental organic chemistry concepts including functional group transformations, reagents, stereochemistry, and mechanisms Explores advanced topics including protective groups, synthetic equivalents, and transition-metal mediated coupling reactions Helps students envision forward reactions and backwards disconnections as a matter of routine Gives students confidence in performing retrosynthetic analyses of target molecules Includes fully-worked examples, literature-based problems, and over 450 chapter problems with detailed solutions Provides clear explanations in easy-to-follow, student-friendly language Focuses on the strategies of organic synthesis rather than a catalogue of reactions and modern reagents The prospect of organic synthesis can be daunting at the outset, but this book serves as a useful stepping stone to refresh existing knowledge of organic chemistry while introducing the general strategies of synthesis. Useful as both a textbook and a bench reference, this text provides value to graduate and advanced undergraduate students alike.

Book Description
This chapter defines risk-taking in organic synthesis as the deliberate pursuit of strategies that do not have near neighbors in the chemical literature. In these ventures into the unknown, chemical behavior can be difficult to predict. The literature of organic chemistry is replete with examples of powerful, bond-forming strategies that had little or no precedent when they were developed. This essay addresses some of those examples in an effort to demonstrate the merits of creative risk-taking in the planning and execution of organic syntheses.

Book Description
K.C. Nicolaou - Winner of the Nemitsas Prize 2014 in Chemistry This book is a must for every synthetic chemist. With didactic skill and clarity, K. C. Nicolaou and E. Sorensen present the most remarkable and ingenious total syntheses from outstanding synthetic organic chemists. To make the complex strategies more accessible, especially to the novice, each total synthesis is analyzed retrosynthetically. The authors then carefully explain each synthetic step and give hints on alternative methods and potential pitfalls. Numerous references to useful reviews and the original literature make this book an indispensable source of further information. Special emphasis is placed on the skillful use of graphics and schemes: Retrosynthetic analyses, reaction sequences, and stereochemically crucial steps are presented in boxed sections within the text. For easy reference, key intermediates are also shown in the margins. Graduate students and researchers alike will find this book a gold mine of useful information essential for their daily work. Every synthetic organic chemist will want to have a copy on his or her desk.

Book Description
This chapter describes the synthesis of two related sesquiterpenes, anislactone A and merrilactone A. We initially accessed a tetracyclic oxetane in the merrilactone series using a Paternò–Büchi reaction but found the compound to be too underfunctionalized to advance further. We then developed an approach based on reductive epoxide ring opening, whereby a fully elaborated C-ring epoxy-cyclopentane, containing five stereocenters, could undergo reductive epoxide cleavage when treated with Ti(III). The resulting tertiary radical then participates in a 5-exo-dig cyclization onto a pendant alkyne to afford the complete carbon skeleton of both natural products. From this point, orthogonal functionalization routes enabled the synthesis of both anislactone A and merrilactone A. A second-generation merrilactone A synthesis is then described, growing out of discoveries made over the course of the first route in the area of cyclopentannulation. An iodo-aldol method was used to develop an approach to the anislactone skeleton and succeeded in producing the BC bicycle with good stereocontrol and functional group tolerance. Further functionalization, however, did not prove possible due to excessive steric hindrance around the incorporated iodo group preventing any productive transformation. This problem was solved by switching the nucleophile in the tandem-aldol process to cyanide. The resulting domino cyanide-addition aldol cyclization was then successfully employed in the formal synthesis of merrilactone A, using a late-stage [2+2] photocycloaddition to access the D-ring.
