ANSI 239.48.1984. Preface The emergence of organic chemistry as a scientific discipline heralded a new era in human develop- ment. Applications of organic chemistry contributed significantly to satisfying the basic needs for food, clothing and shelter. While expanding our ability to cope with our basic needs remained an important goal, we could, for the first time, worry about the quality of life. Indeed, there appears to be an excellent correlation between investment in research and applications of organic chemistry and the standard of liv- ing. Such advances arise from the creation of compounds and materials. Continuation of these contribu- tions requires a vigorous effort in research and development, for which information such as that provided by the Comprehensive series of Pergamon Press is a valuable resource. Since the publication in 1979 of Comprehensive Organic Chemistry, it has become an important first source of information. However, considering the pace of advancements and the ever-shrinking timeframe in which initial discoveries are rapidly assimilated into the basic fabric of the science, it is clear that a new treatment is needed. It was tempting simply to update a series that had been so successful. However, this new series took a totally different approach. In deciding to embark upon Comprehensive Organic Synthesis, the Editors and Publisher recognized that synthesis stands at the heart of organic chemistry. The construction of molecules and molecular systems transcends many fields of science. Needs in electronics, agriculture, medicine and textiles, to name but a few, provide a powerful driving force for more effective ways to make known materials and for routes to new materials. Physical and theoretical studies, extrapolations from current knowledge, and serendipity all help to identify the direction in which research should be moving. All of these forces help the synthetic chemist in translating vague notions to specific structures, in executing complex multistep sequences, and in seeking new knowledge to develop new reactions and reagents. The increasing degree of sophistication of the types of problems that need to be addressed require increasingly complex molecular architecture to target better the function of the re- sulting substances. The ability to make such substances available depends upon the sharpening of our sculptors’ tools: the reactions and reagents of synthesis. The Volume Editors have spent great time and effort in considering the format of the work. The inten- tion is to focus on transformations in the way that synthetic chemists think about their problems. In terms of organic molecules, the work divides into the formation of carbon-carbon bonds, the introduction of heteroatoms, and heteroatom interconversions. Thus, Volumes 1-5 focus mainly on carbonxarbon bond formation, but also include many aspects of the introduction of heteroatoms. Volumes 6-8 focus on interconversion of heteroatoms, but also deal with exchange of carbonxarbon bonds for carbon- heteroatom bonds. The Editors recognize that the assignment of subjects to any particular volume may be arbitrary in part. For example, reactions of enolates can be considered to be additions to C-C wbonds. However, the vastness of the field leads it to be subdivided into components based upon the nature of the bond- forming process. Some subjects will undoubtedly appear in more than one place. In attacking a synthetic target, the critical question about the suitability of any method involves selec- tivity: chemo-, regio-, diastereo- and enantio-selectivity. Both from an educational point-of-view for the reader who wants to learn about a new field, and an experimental viewpoint for the practitioner who seeks a reference source for practical information, an organization of the chapters along the theme of selectivity becomes most informative. The Editors believe this organization will help emphasize the common threads that underlie many seemingly disparate areas of organic chemistry. The relationships among various transformations becomes clearer and the applicability of transformations across a large number of compound classes becomes apparent. Thus, it is intended that an integration of many specialized areas such as terpenoid, heterocyclic, carbohydrate, nucleic acid chemistry, etc. within the more general transformation class will provide an impetus to the consideration of methods to solve problems outside the traditional ones for any specialist. In general, presentation of topics concentrates on work of the last decade. Reference to earlier work, as necessary and relevant, is made by citing key reviews. All topics in organic synthesis cannot be treated with equal depth within the constraints of any single series. Decisions as to which aspects of a vii
