The synthetic chemistry of carbohydrates has advanced at a scarcely equalled rate in the last 25 years, due to the great interest of biologically active natural products coritaining sugar moieties. It suffices to note that in the review by J. D. Dutcher appearing in "Advances in Carbohydrate Chemistry" vol. 18, 1963, only the structures of less than ten aminodeoxy sugars were reported. This book deals exclusively with a single class of carbohydrates, namely the aminodeoxy sugars of antibiotics, the most popular of which is probably daunosamine, a compound for which more than 20 different synthetic approaches have been reported in the literature since the publication of its structure in 1964. No compound in the 3-amino-2-deoxY-L-hexose series had been prepared by chemical synthesis when we started our synthetic work in this field in 1972 on the wave of the successful therapeutic applications of adriamycin. The compounds with xylo stereochemistry were unknown even in the more easily accessible D-series. The size of this book documents the rapid development of the field. I wish to add that the improvements of chemical methodology reported in. the volume outspan the specific field and are of importance in the design of synthetic approaches to other carbohydrate structures. These also include compounds involved in chemical interactions of great biological interest, but hitherto un explained at the molecular level, such as those related with cell recognition, adhesiveness and differentiation.

Due to their specific properties, polymers with well-defined structures have been receiving increasing attention over the last several years. Owing to the wide variability of their properties, these specialty polymers have been used in various areas from biomedical engineering to electronics or energy applications. The synthesis of such polymers necessi tates the use of new methods of polymerization which derived from an insight into the mechanism of polymerization reactions. A NATO Advanced Research Workshop on "Frontiers in Polymerization Catalysis and Polymer Synthesis" was held in BANDOl (FRANCE) in February 1987. Its aim was to assess the new polymerization methods, as well as the latest advances in the mechanisms of conventional polymerization reactions together with their applications to the synthesis of new macromolecular structures. The financial support from the NATO Scientific Affairs Division which covered the "lecturers' accomodation and travel expenses as well as the organization charges of this event gave it international scope. Several industrial companies participate at the meeting and contributed to it success. The organizors who are also editors of these proceedings, want to express their thanks to both NATO Scientific Affairs Division and the companies present at the meeting.

Chemistry and chemical engineering have changed significantly in the last decade. They have broadened their scopeâ€"into biology, nanotechnology, materials science, computation, and advanced methods of process systems engineering and controlâ€"so much that the programs in most chemistry and chemical engineering departments now barely resemble the classical notion of chemistry. Beyond the Molecular Frontier brings together research, discovery, and invention across the entire spectrum of the chemical sciencesâ€"from fundamental, molecular-level chemistry to large-scale chemical processing technology. This reflects the way the field has evolved, the synergy at universities between research and education in chemistry and chemical engineering, and the way chemists and chemical engineers work together in industry. The astonishing developments in science and engineering during the 20th century have made it possible to dream of new goals that might previously have been considered unthinkable. This book identifies the key opportunities and challenges for the chemical sciences, from basic research to societal needs and from terrorism defense to environmental protection, and it looks at the ways in which chemists and chemical engineers can work together to contribute to an improved future.

Synthesis is at the core of organic chemistry. In order for compounds to be studied—be it as drugs, materials, or because of their physical properties— they have to be prepared, often in multistep synthetic sequences. Thus, the target compound is at the outset of synthesis planning. Synthesis involves creating the target compound from smaller, readily available building blocks. Immediately, questions arise: From which bui- ing blocks? In which sequence? By which reactions? Nature creates many highly complex “natural products” via reaction cascades, in which an asso- ment of starting compounds present within the cell is transformed by speci c (for each target structure) combinations of modular enzymes in speci c - quences into the target compounds [1, 2]. To mimic this ef ciency is the dream of an ideal synthesis [2]. However, we are at present so far from - alising such a “one-pot” operation that actual synthesis has to be achieved via a sequence of individual discrete steps. Thus, we are left with the task of planning each synthesis individually in an optimal fashion. Synthesis planning must be conducted with regard for certain speci - tions, some of which are due to the structure of the target molecule, and some of which relate to external parameters such as costs, environmental compatibility, or novelty. We will not consider these external aspects in this context. Planning of a synthesis is based on a pool of information regarding chemical reactions that can be executed reliably and in high chemical yield.
